i am worried about the fins to barrie but on a professional level i thought you might have been more concerned about the thinness of the glass and lack of silicon in some joins
sorry little bit fishy my reference to astatotilapia moorii was about some hybrids i have
can you get clearer pics of the fish
we can tell you what species the fish look like but can't guarantee that that is definitely what they are as so many rift lakes fish can interbreed quite freely
they are african cichlids of various types and some of possibly mixed parentage
though one looks like my astatotilapia moorii, another like my fryeri, then a blue zebra and a peach or red zebra
had reports of 3 others of a similar age doing the same recently
one was too hot another too cold, the other came right with enticement of live food
maybe natural as well
