Appreciate the response. It is sandstone I believe — but I’ll link into that. I’m not opposed to removing it if needed.It is a male, but the brightly coloured rock in the back might be a problem as a backdrop. Fish brighten up or darken their colours depending on surroundings.
If this is a holey rock I'd remove it, as limestone raises hardness and you will mostly want softwater (barely any detectable hardness) for these fish and these rocks are a potential death trap. Had cichlids chasing each other until one got stuck more than once.
I do not know catch location; to my knowledge it is tank-bred, but I will ask the LFS that sold it if they know.It's an iniridae-group species, so for sure not elizabethae. If it's a male, there are not many species in this group with a rounded caudal fin, to my knowledge merely A. iniridae, A. sp. D51 and A. sp. Z12. Do you know the catch location? Did it come with elizabethae?
