Some help please?
Okay, so I'm getting a 15 gallon column tank set up (This one in the link) for a community tank with, for certain, 1 male Betta and 1 Oto. I was originally planning on 2 albino cory cats and 2 upside down catfish, but after doing more research and thinking about the size of my tank (with 7 live plants and 2 decorations that double as hidey holes) I decided to change this to 3 of one or the other. I'm not really sure which one would work best however and I would like some well informed opinions and suggestions.
1 Tank: 15 gal; 2 fish: Oto; Forge. Betta; Tardis. Various plants
2 Tank: 40 gal; fish: 4 Bronze Corys. 4 Mollies. 1 Albino Rainbow Shark. 4 Guppies. 2 snails. 3 cherry barbs. Plants out the Wazzoo
