Today I went to the pet shop and got a goldfish. My tank is 20 litres, and the goldfish is pretty small. When I first got the fish, it was gasping and eating the bubbles in the bag. I thought this was normal. At home I let it acclimate and everything then I put it in the tank.
It is swimming fine and not rapidly breathing but it goes to my air stone and filter and eats the bubbles. I don’t know why this is happening because I have enough oxygen in there and I know that.
I have an air stone and filter. I think it might be because one of the suction cups that was holding up the filter got loose and the goldfish keeps on eating the stuff on that so maybe it needs more air to supplement the food it’s eating or something like that. I have no idea.
Is it maybe just because it is stressed and hasn’t got used to the place? Please help I don’t want him to die. He doesn’t go up to the surface too often though like maybe a few times every minute. Please help though
