Baby African Cichlids 20 Gallon Tank Question

[Thomas831]

I would like to know how many baby African Cichlids I can safely keep in a 20 gallon tank. I plan to upgrade to a 75 gallon tank, as soon as they grow in size(aprox. 6-8 months). I am currently have 1 demasoni, 1 bumblebee, 1 yellow lab, 1 tropheus duboisi. I appreciate all of your feedback in advance. Thanks.
