I already have a 10g that's been set up for a few months...it's been switched around a lot I started with harlequin rasboras but now it currently houses nothing.. For plants I have green cabomba and wisteria, which are taking over the tank. It's about 2 watts per gallon of light, I have seachem liquid co2 but I don't use on the 10g....anyways I would really appreciate any thoughts as far as plants and fish go..I'm sorry to say my betta Richard passed away after a long happy life of 3 years :c. I really love bettas but I'm looking for something new to put in the 10g, and I already have tons of corycats in other aquariums..
