Hello, I currently have a 20 gallon long tank sitting empty. I have a cave, and coconut hut, a balsa wood piece, and a few fake plants ( i do want real plants but I don't think my light is good enough). I know i want to turn this into an apisto breeding tank. I don't know what species, that's one way I need your help! Also, if you could suggest a filter and any other thing you can think of that will allow this to become a successful breeding tank let me know ! I have a 50 watt heater ( two actually) will this work for this size tank? And if you have a good light for plants let me know! I do want some plants. Thanks!
