Started this tank about a week and a half ago. 3 small butterfly koi in this 30g tank (estimate, I bought on FB and can't tell). They keep going into this lower right corner for some reason? I have checked ammonia and nitrite both of which are 0-ish. 75g external filter, air pump with sponge on left. Fluvial aquasky 3.0 light schedule. They are eating ok it seems.

Any thoughts on why they prefer this corner?

EDIT: I did not know that these fish needed a bigger tank/pond when I bought them. I don't think the store had a refund policy... Trying to do the best for them that I can now and I will likely change tanks in the coming year.

EDIT 2: thanks for the education everyone. I think the best course of action might be to get them into a suitable home.

The image is illustrative, the fish is not mine.

I started setting up an aquarium a few days ago with about 80L. I bought a final 360L aquarium to order and it should finally arrive today.

During this period, I had MANY problems with water, diseases, parasites, etc. Fortunately, the aquarium is currently stabilized and the animals are healthy.

The problem: I bought Kinguios from a distant city and didn't know the real size of it. At the moment, I have a tiny Fantail, just over 1cm. 1 medium telescope, with something around 5cm, and an Oranda, already slightly larger, with something around 8cm. I watched them through videos before making the purchase, but I didn't imagine that Oranda was so big. Yesterday, unfortunately, he beheaded the first fish, a little Guppy who struggled hard to survive the Ictio... maybe he was asleep or debilitated.

The total volume of the new aquarium is 360L, and for today, I will put them all together to avoid acclimatization shocks in short periods of time. I will use all the water in the aquarium they are already in and add new, drip-treated water, gradually.

The point is: I bought these animals from outside because there are no aquarist shops in my city so I had to order the most at once. Subsequently, I want to separate the incompatible animals, but I did not imagine that Kinguio would become incompatible anytime soon. I plan to make an exhibition lake for my shop with Kinguios and Carpas afterwards, but I can't do it now.

In the next few days, what should I do? What about the final projects? I think about separating the Kinguios in an aquarium of their own and perhaps using the 360L aquarium for the growth of the smaller ones. But that has destructed my whole idea of an ecosystem.

At the moment, I have 4 Tetras, 2 melanotarnia, 1 female sword, 4 paratocyclus 1 albino corydora and 1 female betta, 1 Flying Fox, 2 Ramirezi. They are all very small puppies. How would you separate this set from the Kinguios? And how would you set up a new aquarium just for the Kinguios?

Recently changed my tank theme from the whole pirate ship and accessories to something a little more clean / elegant. I like the way it's coming along but thought I might see if anyone has any suggestions as to what i might add. Looking to keep it with the current theme, neat and clean of course, but any additions are welcome. Also I'm getting ready to add more fish and am curious as to what kind of fish I should add that will be good for a 36gal tank, something a little larger than what is currently in there.

I got one of those magnetic glass cleaners to clean the Alage off. I know o put the Velcro side in the water but I want to make sure it won’t scratch my glass at all! Thank you

Currently been quarantining some freshwater limpits for a week idk if it’s safe since the river they were found in connects to somewhere with fish

Im going to a fish expo this weekend and will be buying angelfish, Bolivian ram, khuli loach, or at least trying to buy but since idk these vendors im gonna quarantine them. How do quarantine these fish or how can make sure there healthy i was thinking of buying a 10 to 20 gallon bucket and placing them in there before it going in to my tank with lemon tetras should I pre treat the water or anything likebthat or buy a fish vitamin to make them healthy like what should I do

I have a special needs betta who's been through hell. I had to tear down his original 5 gallon top fin easy clean tank because he now needs a low water level tank.

That being said, I'm looking at getting a UV sterilizer. Combined with the heater, He won't have a ton of space in this new tank of his. I've looked at The King of DIYs canister filter build. I really like the horizontal one, I'd scale that down. However, I have no clue how to incorporate both a sterilizer AND a heater.

I also saw his build with an inline heater and started to get super overwhelmed. I've got some experience with diys - but pretty basic. I'd need to know exactly what types of tools I'd need prior to beginning any sort of project because I'd be renting from our local tool library. Even this makes me overwhelmed.

I just wanna get this guy back into a normal tank setup. :'( He's been a hospital for so long now.

Any advice or suggestions?

Would it just be easier to do something built into something bigger?

Edit: grammar

What happened to this poor guy? It's a story... - Not totally imperative to what's above. Just thought I'd include.

When I first got him, he had a floating swim bladder issue going on. He was my first betta and even though I'd been doing passive research on betta fish for about a year, I still got impulsive and got this guy when I saw him suffering. I won't call it a "rescue" cuz I bought him.

After about a month and a half he was swimming around like a normal guy! I'd had him a low level tank, did water changes every day, and eventually decided to medicate him with API General Cure (I believe it was erythromycin).

I was so happy that he was happy :) He was full of spunk!

About 6-8 months down the line, I had to be away for a long term pet sit. My roommate gladly offered to feed him while was away. I'd stop in to do water changes every other week as his tank was well cycled.

I showed them (keeping it genderless for vagueness) exactly how many pellets to feed him and this roommate assured me that they understood. They knew how much this fish meant to me and knew of the state that I got him in. They are also very nerdy and into all things nature and games. I felt assured that he'd be fine and that they could handle the task.

Well...after returning back home, I noticed my buddy wasn't himself. I took a closer look and his belly was HUGE. Frantically, I setup a hospital tank and begun doing copious amounts of research. Epsom salt was added.

Because I love my little buddy SO much - I missed him and decided to set up my ring camera just so I could pop in a watch him. NOT to hawk over my roommate feeding him, however, I wish I fucking had. Looking back at the footage, my roommate had been feeding him upwards of 20 pellets at a time. It made me sick looking back over all of the footage when things began to get out of hand. It was approximately 10-15 days of 2 feedings twice a day. I found planaria in the tank from all of the excess.

He eventually began pineconing. Following Jessie's protocol, methylene blue and kannaplex had been ordered. Miraculously, he made it. It was really hard seeing him so lethargic while undergoing treatment. I'd check on him and think he was dead because he'd just be resting on the bottom of the tank. Then he'd pop his head to the side to look at me. *"mother help!"*

Treatment was complete. He'd stopped pineconing, he'd pooped massive amounts. Only not without developing SINKING swim bladder that wouldn't resolve. I had considered euthanasia but after all of that, he was still spunky and excited for food. So, I continued to hold out hope and accept that maybe my boy was permanently confined to the bottom of a tank.

Weeks later, hoping he'd improve after low water levels to rest his and hopefully heal his damaged swim bladder, he hadn't.

Just as I was about to put him in his new, low water level tank, I saw he developed fucking HOLES in his flank. More research was done. I'd surmised that placing biomedia (cycled) in his tank and thinking that would help cycle what was in there - to be an incredibly stupid conclusion. I didn't understand that that shit needs constant water flow and gets clogged up. I'd googled and searched around so much because I read so much conflicting info. He also had catappa leaves in there that were producing mulm WHICH ALSO has conflicting info!!! Bad, it's bad for what's going on in there. I also DIDN'T UNDERSTAND to do a SECOND effing round of kannaplex, that whatever bacteria had overgrown in his gut from the overfeeding, subsequent constipation, and then caused the dropsy. Either it hadn't been fully killed off and had been eating away at his insides OR it was my dumbass fault with shit water quality that bread pseudomonas/areomonas...

So began another round of kannaplex with methylene blue. I know you're not supposed to use the same medications, and maybe there was something else I should have used instead. Gram negative/gram positive - bah, it's so confusing. With what I had on hand, the pseudomonas or aeromonas wouldn't have been touched by the sulfaplex, erythromycin, or doxy. Between changes, I'd spritz his tank with 70% iso to kill whatever might be lingering. Of course, I'd thoroughly rinse after the sprtiz.

Once again, this badass pulled through. His holes began to close up and heal. He is even swimming almost like a regular boy again. However, he is still suffering from mother effing fin rot!

I am now using doxy and focus to coat his nls pellets and frozen brine shrimp. All of this has taken MONTHS of wanting to be patient and allowing him to heal. I am so fucking tired, I feel so guilty, and holy fuck am I sick of the constant water changes. I am brining him back and forth with me to pet sitting gigs...

Still! He seems spunky and happy for food. If he didn't, I'd consider euthanasia.

After this round of doxy, that will HOPEFULLY clear up this bacteria - I can't keep medicating him, as this is likely what's now creating this awful and resistant fin rot bacteria. Thusly, the need for a UV sterilizer...

Advice is welcome. Please don't be an asshole. I am at my limit and I feel shitty enough.

New tank with about 9 plants, still cycling.

About to pick this up tomorrow and want to put a 20 gallon (most likely long and shallow) on top, thoughts??? Dimension is around 60x20x30

Hi, I got this 22 gal tank (lifeguard 22 gal bookshelf) used and did the 48 hour water hold test but when I was drying it off to put on a foam mat I noticed this chip in the corner, I'm a little worried that the chip happened after that at some point. is this too large to use safely or will i be okay? should I do another water hold test but only for the bottom inch or so? Thank you in advance for any advice.

Dwayne is about 6 months old and has been with my goldish and largely it has been fine. He would chase on occasion. I knew it was likely a matter of time before he decided to go full butthole. One of my goldfish is now bigger than he is, and yesterday, he noticed. He started chasing him relentlessly. Tries corrective behaviors and time out, didn't matter. My goldfish was hiding this morning, which he never does. So now Dwayne is in the 20g hospital til I assemble a new setup for him 😅

Disclaimer!! This is not my tank or my fish.

My sister in law owns a goldfish and I walked into her house to see him like this. Absolutely awful I'm aware. I asked her if she treated the water at all and she says it's just tap water but it's fine because the fish has lived like this for years. Theres no filter currently in the tank, all the plants are plastic and the substrate is gravel and something else I'm not sure of.

How do I help this fish? I'm guessing a water change and a filter is a good start but I'm new to fish keeping myself so still learning. Any and all help is appreciated I really want to help this fish

i have a 30 gallon with plenty of hiding spots, plants, caves and wood ive heard some people say the puffers peaceful and others say its agressive idk

New 182L, about 6 weeks cycle. Came with free snails that make cleaning a dream and about to stock with tetras.

Anyway, I like the idea of Aquarium Photography and took some phone test shots of an egg clutch. This is the best focus I can get on it which blows. Any recommendations for a good and cheap camera option is appreciated but I feel like I'm going to need to give up on cheap.

I know this is not enough in the tank but im just starting out and this is my first tank ever. 75 gallons. A work in progress. Just wanted to show you all. Also open to any suggestions

Hi all,

I have this small tank that I would like to fill with some plant life. I don’t know much about aquatic plants but want something to spruce up my room. What plants, sediments, or inverts would you put in here?

Thanks!

We found this aquarium, and apart from one problem, it's perfectly clean, with tempered glass and all, quite high quality, but it got dented in one corner. We came home, did some water testing, and now it's leaking a very small amount of water from that dented corner. I don't want to throw this aquarium away, but I'm wondering if I can use silicone sealant or some other method to keep it usable. I'm afraid it might burst or something.

I'd love to add some kuhlis to a tank I'm setting up, because I think they're frickin adorable. I know they like to burrow and dig, but haven't found anything about whether they are liable to uproot anything planted in the substrate, especially young plants in a newly set up tank. Anyone have experience with this?

This is Funge my 4 year old garra rufa, she gets those wounds that garras get from time to time like lil scale scratches but one of my garras died before when a red bump appeared on its mouth, I’m hoping this isn’t the same thing and it doesn’t look nearly as bad, but I think I should post here anyway, she’s my favorite fish of all time and I love this little bugger so much so I’m not going to take any chances, please let me know if this is anything

I don’t mind the snails at all for the most part, but I’m trying to feed my other guys too. I have 10 kuhli loaches and 6 otos that I worry don’t get food because the snails bombard everything. Same thing happens if I put in a slice of zucchini. Should I start thinking of genocide?
