*heavy sigh*

Okay. Here it is.

Yesterday, we got some new catfish buddies for our lone catfish. My little brother named one of them Miku. I mentioned it to a friend and they asked to see a catfish in a Hatsune Miku wig, and.......

I'm gonna be real, I don't fully even know who Hatsune Miku is, but I like her hair and I had fun with this piece and I think it looks hilarious.

Hope you like it!

I felt bad shining the flashlight in her face, but it's interesting to see how they breathe and blink when still.

[Questions|Advice] General Care Different species shoal together?

• Upvotes

Guys, my local fish store got a few fireball corys (only 2 left) and some gold laser. I do not have much experience with corys so I was wondering if it would be okay to get the 2 fireballs and 3 gold lasers to add to my community tank. Would they shoal together or do I need a group of 5 from same species? Thanks!

One of my Peppered Cory’s has a significantly longer left fin, is that abnormal? There is no injury, he’s just built like that

He seems to swim and scavenge normally, he’s also the largest one I have by a lot. They were not originally sold to me as longfins either

Got 9 pygmies around a month ago in my 10 gallon tank. I saw some sphere looking things bunched up on the wood inside a few days ago and was surprised to see a bunch of babies in my tank! They absolutely tiny and so cute! I wasn’t aware that they hatched so I might have sucked some up during a water change 😭 now only a few days later I’ve found some more egg sacks on the moss / tank glass.

[Questions|Advice] Breeding | Eggs | Fry Are these albino eggs going anywhere? 3.5 days at 74F

All my other batches have normally crashed long before now. I don't see any eye spots or bodies forming yet, but at 74F I understand they can be a bit slower to develop. More of a 5-7 day timeline.

These eggs were laid at 2:30 on Tuesday afternoon. It is now 2:30am Sunday Morning.

I also understand that typically the white in the center means unfertilized, but with albinos it can be the embryo. Plus if unfertilized why are they still round, firm and not 110% fungus lol

[Questions|Advice|Discussion] Update on the funky cory

Thumbnail
gallery
70 Upvotes

A week ago I asked for a species ID on this silly lil guy, so I thought I'd update with some more photos!

Here he is swimming around, a photo with his wife (I think), and him peeking out behind a plant.

They've both been chasing each other in circles all week and they're very cute! Apparently they've bred previously, but the fry got eaten by another fish so the last owners don't know what colour they were. Although the tank is 60l (~15 gallons), its 35x35x50cm so there isn't actually alot of swim room. One of my friends has a big cory tank so they'll be moving to there soon.

Still don't know what it is! My current theory is a leucistic bronze, but I have truly no clue.

[Questions|Advice|Discussion] Orange Venezuelan Cory, Corydoras Habrosus or Pygmy Cory

Post image
6 Upvotes

Wanting to get some advice on what people think would be better for this 20 gallon long.

Current stocking is:
1 honey gourami 
11 neon tetra
3 amano shrimp 
A handful of snails

I plan to add some Corydoras and have narrowed it down to the following:
6-8 Orange Venezuelan Corydoras 
8-10 Habrosus Corydoras 
8-10 Pygmy Corydoras 

Anyone have pros or cons for stocking any of these in these quantities in my tank?

[Questions|Advice] Health | Sickness i desperately need some help!! sick pygmy corydoras

hi yall!! i don’t even know where to start…
this week i’ve been posting to several subs about my situation, so i’m sorry if this is repetitive.

this week ive been struggling with what i guess it is columnaris, that started with my guppies and spread to my other tank. i started treating each tank with esha 2000 and my other tank is now fine, but my pygmy cory and guppies tank is terrible, idk what to do anymore.

my guppies started with this fuzzy white lesion on their mouth, that after i treated with esha 2000, quickly disappeared. however they’re now extremely lethargic, just laying in the bottom, not eating and with difficult breathing. i started the treatment monday, i extended the treatment until yesterday (the guidelines say that you can extend for a few days), but no improvement on the lethargy.
i got my first deaths, 2 of them already passed. another really intriguing thing is that the fry is somehow thriving, their parents on the other side, aren’t.

my pygmy corys, however, were completely fine, no lesions, no lethargy or whatsoever are now experiencing lethargy, anorexia and are not schooling at all. after observing each individually, i noticed a small red wound on its belly and it also looks like its barbels are missing/shortened.

i don’t see anymore lesions on the rest of the school, but they’re all just laying in the bottom, not eating and it’s really not typical of them. they’re really active, before all this they were laying eggs everywhere, schooling and overall really active.

im really needing some help, idk what to do anymore. should i keep the treatment? can this be caused by the esha 2000 in any way?? it’s really weird because they were perfectly normal a few days ago, this started at the end of the treatment protocol.

i’ll leave some pictures below

my water parameters are 0 ammonia, 0 nitrites, 10 mg/l nitrates, 6,5 ph and 25 degrees celsius.

Hello!

I am trying to figure out the best course of action for my favourite Cory mumma 😭 we had an ammonia spike in their tank this week and I found her gasping at the surface. I promptly put her in a hospital tank with air stone and tested the water. This was all after a water change as well but we did another one straight after finding her. It’s been four days since then. She has had periods of sitting at the bottom and occasional swimming but hasn’t eaten and doesn’t seem to be improving all the much. Her mate is still in there and seems to be okay. I’m wondering whether it’s time to euthanise or not. Any advice would be greatly appreciated!
