Thanks so much for your opinions !!!
The water in tank 1 is @ 81 F and small tank is at 77 F
I do 10-15% water changes bi-weekly whenever possible.
I worried about the betta at first but he's been in the tank for a year and thrives
he and the red paradise are always rubbing against each other ( almost flirty) and theres a bunch of floating plants on one side that break the filter flow and they like to hang there when not playing. Hmmmm.... If I can get the geophagus to accept the catfish, I'd have room to get them a school going. How much room do you think I have in there? Have to think about the tetras though...
