I bought 8 Zebra Danios for my 125 Gallon tank. They are now the only ones in the tank and seem to be having a ball. I w3as planning to have a true community tank, but I'm thinking that fish are probably more happy just with their kind--causes less stress. I plan to add 8 peppered corys and I'm thinking like 8 golden danios. What do you all think? Thanks.
The only time I've seen danio "look" comfortable was in large groups, they seem very spastic otherwise. Personal opinion.
I once bought a lone "glo" zebra danio because it was alone in a tank at my LFS forever.
Lollypop was, and hopefully still is, pink and yellow. It got along fine, I guess, with my minnows as far as aggression goes...but my minnows group flow was interupted. Then I kept it in a tank with a large Mystery snail and a couple random tetras that remained after my Great Grean Neon Tetra Tragedy of 2019.
Lollypop, ever the zippy one, ended up getting overweight because I overfed trying to make sure the two tetras got some. The neons didn't make it. Hard lessons.
I really needed to shut that tank down so my LFS took Lollypop back, put her (?) on a diet, and about the same time got a new shipment of "glo" fish. I visited Lollypop for a few weeks and felt great about how she was finally in a group with others and she looked so happy....and then one day she was gone!
Turns out a little girl came to get a fish and picked out Lollypop out of all the others.
The thing is she took JUST Lollypop!
I have to laugh.
Sorry for the tangental response, I'll never forget sweet spastic Lollypop!
I like your idea of species only and admire you for considering it. Even if you have q community tank it sounds like you'll have room for a big group! Can't wait for pictures ♡
