What would you put in a 29 gallon? It was suggested that I do 2 goldfish, but I don’t know if that’s a large enough tank? Unfortunately, despite my medicating, camallanus worms wiped out my entire sorority. As of right now I’ve decided to keep only my 5 gallon with a single betta. This way I can keep a closer eye on him/her because they seem to be really susceptible to illness. I don’t want to lose any more so I’d like to fill my 29 with some more hearty fish that don’t get ill as easily.
