So far I have 3 malawi cichlids to be transfered from a 10 gallon -----> the 45 gallon. The three are anywhere between 2" to 2.5" long. Are there any other African Cichlids that are compatible with the garden variety Malawi's?? I don't know the latin term for each of them, but if anyone could, please give me a good ratio and common name for compatible species. Thanks. PS: What are "good" tank mate(s) for a 2.5" black convict in a 29 gallon?
