I would say you are going to have trouble with that many cichlids in that tank for sure. Personally I wouldnt put a pair in anything smaller than a 20g. Be careful with tankmates also--they get a little nasty when they are spawning. This is for the pulcher--Im not familiar with the scarlets--I assume the same is true for them though.
I love my kribs and wish I could have alot more of them.
