your tap has ammonia?!? and yes def feed 2-3 times a day when he is little, i continue to feed twice a day with all my cichlids but some people go down to once a day once they are bigger (5in or so) as long as you keep up with wc then a uv sterilizer shouldnt be neccessary, especially since its a bare bottom tank, also you didnt say, so i am going to go ahead and reccomend you treat him with all 3 rounds of jungle parasite clear since you got him from a lfs, i think yours will do fine with 50% once a week, thats what i did with mine and he actually enjoyed the big water change and would swim right in the stream of new water (that is until he killed himself in a shell

)
