I buy 100 Rosies every Fri. and of course I have multiple breeders so I always have the best food for cichla imo.. 3'' Cichlid's. All of my growout's are around 5''-6'' so i am now trying shrimp. - 55g BW/Krill/
I feed them 25 Goldies on the weekend. Primarly this tank get's pellet's/shrimp as there main staple for food. The Cichla in this tank are 8''-12''. -150g BW/Krill/Cricket's.
Of course feeding these guy's is ridiculous, I feed them at least 50 XL goldies at least on weekend out every month. Sometime 2x a month. The Cichla in this tank are 14''-20''+. This tank has been going through some trial and error. I have been trying different feeding options. I feed them massivore which they eat but it's very messy so this tank get's about 30 large shrimps every Wed. and Sat. Every here and now I get a good size unwanted Cichlid/Koi/Gold fish that I feed to them at least once a month or when ever I can. - 240g ( also feed talapia/mussles/Krill Frozen and dry/ and any fresh caught lake fish I can catch)
Angler at the size your Cichla is at you should start feeding more then just feeders for sure.
