Hello, At present I don't own any GF. But I am a old aquarist. Like many had GF when young and they didn't live long with our mollies. Older and wiser now so doing my research for future. At present I have a 75gallon tetra tank with canister filter and it's planted with swords. Thinking after Tetras pass there a few years old now, I would like to get couple GF for a change. So doing my research for that future time.
