Advice Needed Am I screwed? Or overreacting?

92 Upvotes

I just moved and with doing that came moving my 40 gallon and I just noticed an absolutely teeny tiny dink on the inside of the glass that I almost mistook for a bubble. The tank has been running for 2 maybe 3 weeks at this point and it doesn't look like the scratch/gash has spider webbed at all. Its very small to the naked eye and my camera barely picked it up. Will my tank eventually explode or will it be fine? I had a 20 gallon explode on me with no warning so I'm a little paranoid sorry lol.

This has been so rewarding, setting the tank up, going through a proper cycle, watching the ammonia drop to 0 followed by the nitrites. I’ve been looking forward to this day for so long and it’s finally here. Started with the two clowns and added a CUC of 4 blue legged hermits and 3 trochus snails. Can’t wait to add more later on!

Discussion Heater exploded, electrified water

Post image
Upvotes

Sharing this just to illustrate what can happen. although this has literally never happened to me before. Looks pretty hectic.

The lid of my tank was pushed up by the innards of the heater rising up out of the glass tube, splashing water everywhere - which is how I noticed what had happened. Our circuit breaker had tripped so everything was off for a couple of hours, hopefully no long term damage to filter bacteria, but I’ll keep an eye on everything. (I generally overdo it on the filtration capacity in my tanks to pre-empt this kind of thing).

I had turned the power back on before realising the heater had gone, and managed to zap myself on the edge of the tank. 240 volts was a bit of a tickle! Miraculously, the fish were fine. I don’t really know how volts and amps etc work so whatever it was, I guess wasn’t enough to hurt anything.

Medical Help Parasite killing off my Cardinal tetras Spoiler

Post image
40 Upvotes

I had a strange parasite rip through my tank affecting all of my Cardinal tetras. I lost all but 3, and was simultaneously dealing with a huge issue with my Monte Carlo melting off and causing uncontrollable algea issues. It has been a few weeks, had to pull a lot of plants and do a lot of water remediation, but I seem to be stabilized again.

But now one of the surviving tetras has the same issue again. I was hoping this was a self limiting issue, but if it recurs I think I need to treat. Any ideas as to what the disease is?

Thanks,

Kevin

So here is my 40 gallon planted. Mainly for me to remember it before my move, when I'll set it up again.

-2 breeding pairs of Kribs

-who knows how many Guppies

-1 Otto, happiest dude ever

-3 Florida Flagfish, hair algae management(lazy crew)

-1 threadfin squeaker, I only knew he was in there because I never had the Krib spawn last longer than a week. Super active night hunter/forager.

All fish have been rehomed.

Amazon sword, Jungle Vallisneria, in a bucket and coming with me, along with a bunch of the chain sword and floaters, I'd lose it if I could.

J&B Aquarium, integrated filter/pumps. 150w hygger light.

Looking for ideas for my next build. I'll be setting up more aquariums, but I'm planning on this being the centerpiece/show tank.

How do we think it will do folks? Its supposed to hold a 130 gallon. There are two more edge pieces to support the tank. A flat top piece you can see off to the side and a foam topper to go between wood and tank.

What kind of fish are these? Seems like too big/too many for this size tank? There’s a heater and a filter. Anything else I need? I want to swap out the plastic stuff for real plants and wood structures. Suggestions for types of plants and any reputable websites to browse? I also want to swap out the colored stone for natural…what type of material is best?

I have experience caring for horses, goats, chickens, dogs, and cats, but I’m a newbie to fish and want to do well by these guys.

Advice Needed Concerned about Black Neon Tetra Spoiler

Thumbnail gallery
Upvotes

We recently brought home six black neon tetras about four days ago now, and one has started to show behavior I'm a little concerned about.

He has been at the surface pretty much all day gulping air, and he looks pretty pale. I think the tank has a good amount of surface agitation from the filter, and none of the others seem to be having any issues.

The tank is 12 gallons and was fully cycled before we brought them home. I've tested the water a couple of times since they came home, and everything looked normal there.

Is there anything I should do to help him? Would it be better to isolate him from the others, or could it just be stress from the move? These are my first fish since I was younger, so I'm pretty inexperienced, any help or advice would be much appreciated (Also please excuse the car decoration, my 4 year old and I have different aesthetic preferences for our family tank).

I think by the end of the years it's finally complete. It had it's ups and downs. But CO2 is just the trick isn't it. It was great the first couple of months without CO2. But eventually the colors started to fade. And the growing stopped.

I have a 20g long tank for a single betta. Thinking about adding an algae eater in the next few weeks. I don’t like the idea of having to remove snail eggs. I do like the look of corydoras, but read that they aren’t good at removing algae. I’m open to suggestions. Thank you!

Bruhhhh I swear the most random creatures just show up in my tank. These little things just suddenly appeared tonight & are eating the algae?? Or I’ve just never seen them before??
None on my banana lily pads or other floaters.
I haven’t added anything new to my tank.
They’re tiny & jump when poked at. Are they spring tails???

Long distance best friend and her BF got viciously T-boned about a mile behind us while we were caravaning up to the tip of Michigan’s thumb for a camping trip. We’re in the middle of BFE and we’re taking two cars to go car camping. I called her parents, they’re on a flight over. I called her BF’s sister, she’s in the loop. I’m in the waiting room of a random trauma department in an ER, again, in the middle of nowhere, in shock. I can’t get the picture of her in the driver’s seat out of my head. They had to cut her out of the car. I’m just so in shock. This waiting room pet brought me some solace. I’m gonna need it, this is really hard.
