Looking for a small, slow fish that stays in the upper or middle part

[Mazain]

Yeah I have them and I doubt they are good for small tanks. And they spend their time on the top, but eat all over. Gluttons too.
I am no longer looking for the fish for my 25 liter one, it would be tempting fate but thanks anyways.
But glad you mentioned it, this is one of the fish recommended for small tanks and I do not think it does well in them. I have them in a 150 liters and they are all over. Good swimmers too, I keep them in quite a current. How do they behave in small tanks, isnt it the case with them like with neons that they can survive small tanks, but do way better in the larger ones? I mean they are not even so small why are so pushed for 50 liters

This probably spawning or mating happening as they lay their non adhesive eggs between sand and river stones. Mine are kept the same mix with whites and golden.

I appreciate the care you are showing for giving your fish what they need, instead of trying to fit them into what you need. When it comes to tank size, I believe a species' activity level and social needs matter at least as much as individual size.

If i am not mistaken, they are forbidden here in the EU. From the pictures I have seen they look like some sort of a kids toy and not a real animal, but I mostly see them in the tanks with colorful pebbles so it maybe just looks that way

Not banned in Canada! I used to own some after someone gave them away to me.
They do look unreal, bright neon colours.
Why some guy thought it would be a good idea to make them that way, I dunno..

Thank you that is very kind of you to say I guess we have to learn something from the hobby eventually

Green Glo danios were the first to be developed to help with research in polluted waters. It was hoped to further develop the technique to produce fish with genes which caused the fish to fluoresce in response to certain toxins. They were not developed for aquarium use Then someone with $ in their eyes thought it would be a good idea to market them in the aquarium trade and they were so successful they developed other Glo species.

That’s fascinating. Another example of how technology can be put to both good and bad uses.
