Or more accurately, what are some good midground plants. I have a 75 gallon, EI dosing, 4x54 T5HO but mostly just run 2x54, pressurized CO2. I have a corner of the tank with L cuba in the background, L brasiliensis in the foreground and a java fern in the middle. The fern is becoming too large and I'd just like a change so what are some good midground plants? Thanks!
