Not sure on the male. There were three in the tank. The femal was the smallest by far, maybe 10" and quite thin. I had had them all for at least 3 years by this point.
The water params were:
pH 7.2
GH 0
Temp 78-80
At this point I think I was doing weekly 50% water changes. The tanks was heavily planted and had a ton of driftwood in it.
Feeding was mostly beefheart.
