Hey folks, is there a max harem size for Apistogrammoides pucallpaensis in a 20 gal? All of the articles I can find seem to be from the 90s, so it's hard to get reliable info. They all say 8 gallons is good for a pair or trio, but I'm dubious. I guess they are a bit boring looking, so I'm not surprised at the lack of info, but my lfs is flush with females right now.
Also, as I have a good amount of spare space in other tanks, how many females can cohabitate in a sorority?
