I tried to get a female. Bit of a short and wider body than my male. I have a 10 gallon with a clear divider between them. This one doesn’t seem aggressive at all and likes to hide while my male flairs and shows off. I’ve had it for about 5 days. The male built a bubble nest last night which is a rare occasion. He’s only built a few before in the past 6-8 months I’ve had him. and he’s always been alone in his tank.
