Air in baby Danio swim bladder
Hi, I am new to fish keeping, I have a big tank set up with 2 danios, 2 minnows and a goldfish. My danios bred approximately 6 - 8 months ago. I was oblivious until I found 17 babies when cleaning the tank. Of these 17 I have 5 left. I keep them in a small fish bowl, with no filter but do a 25% water change every day and am careful not to overfeed them. I feed them on tetra mini food. I don't want to feed live food.
My worry is, 1 of these babies spends his life floating on the top and has been this way for a few months. He struggles to swim and goes in spirals. I can actually see an air bubble in what I assume is his swim bladder. I've tried peas and putting a salt solution in the water but he's no better. He eats etc but I feel very sorry for him.
The other issue is 2 of the other babies have kinked tails which both appeared overnight at the same time.
All advice greatly appreciated. I have nothing to test water pH etc, and to be honest don't want many more fish. I acquired my adults from my brother who no longer wanted them.
