Exo Terra Silk Plant ... bought for use in aquarium, as was used at aquarium store. Hidden suction cup on back. One Large - 25" One Small - 15".
A bunch of miscellaneous things. Fluval Edge gravel cleaner, rarely used. Bought ,but needed larger cleaner.
Misc. Stuff and Air bubbler things,
To many cichlids in the tank depending on the size, not enough water changes and filtration. I've heard those liquid cycling bottles they sell at LFS
I find it rare to hear people say that there Betta Sorority tanks are peaceful. Good luck with them. I love bettas.
I agree with the above posts. Minimum 2.5 gallon, a low flow filter, gravel or sand your choice and a heater.
