Okay. I'm a total novice. I have a 125 with 6 Labidochromis caeruleus and 6 Iodotropheus sprengerae, all doing well. I am considering adding a sextet of Cynotilapia afra. How do you handle feeding? My labs will eat anything! And they are agressive feeders. So how do I feed the Afra, if I go that route?
