I had 2 minnows for a couple of months and I kept them with 1 goldfish in a bowl. Can I put the minnows in with my tropical fish? I know that you can't keep goldfish with tropical fish but what about minnows?
That poor goldfish should not be in a bowl, goldfish get BIG, goldfish need at least a 20g tank and here is why:
Yes, you can keep the minnows with your tropicals... but PLEASE find that goldfish a better home, being in a small bowl like that could stunt him, deform him, or kill him. When goldfish don't have the room they need, their outsides may not grow, causing deformations, but their insides will keep growing, and this causes death.
