1st thing,
your tank is way over stocked!!!! that is sort of ridiculous dude. 9 fish in a 10 gal? let alone 9 cichlids!!! that is way too much.
2nd thing,
your temp seems a little low. and your ph is for african cichlids.
3rd thing,
it seems your fish had what i call tornadoe disease. i had many cichlids get this, and i believe it was from the excessive beatings it took.i had a auratus go bezerk in one of my tanks a while ago, and many of the cichlids had these same symptoms. i think the fish is done for. and you better get ready for some more bc your tank is too crowded.
