My temp dropped down 10* in my tank because the house heater was not working last night and helping with the temp in the tank. It went from 80* to 70* my betta looks a little sick I'm trying to bring it back up to temp.
Can't wait to see the tank when those plants take root. The green will pop more with brighter lights, but if you are dead set on a carpet, you will need another high contrast color to replace the black of the eco-complete. Cabomba furcata, maybe? :3
