Go with the labeotropheus and 3m:9f saulosi.
If they are at least 1.5 inches they should work.MahaB said:My Labeotropheus are around 4 inches, but i could find only juvenile saulosi in shop. Is it good to stock those?
Not likely, and it could make aggression worse. I thought you were going to rehome everyone but the labeotropheus and the new saulosi? I would rehome the others before any move.MahaB said:Im planning to shift the existing and new mbunas at once to the new tank, does it reduce the aggression?
