In a 55g growout i have tiny cichlids, 1 jag, 1 jd, and 2 servums not sure on kind but a light green color, all about 1-2" , and also 1 senegal birchir. I feed them a cube of bloodworms once a day, should that be twice and is there any other foods that i can give them? And also how much of a wc should i do is there a percentage i should be changing? And also what is the expected growth rate on each of those fish?
