I have recently purchased a 150 gallon (72"x18"x27") and decided to take the plunge into cichlids. I have had numerous tanks over the years, but most of the inhabitants were friendly schooling fish, but most seem pretty blah. Anyhow, I'm currently doing a fishless cycle, so i have a little time to find exactly what what i want. I've found that I like the looks and temperment of the malawian cichlids, and I've decided that I would like some yellow labs and around 14 Demasonis. I am currently building up a rock wall with plenty of caves to hide in, along with some plants (would perfer silk, but i have a large planted tank i can steal some java ferns/vals/etc from). PH is at 8.2, which is in the malawian range from what i read. After all this babbling, my questions are what else (if anything) can I put in with these guys. numbers of fish and the simpleton name along with the scientific name would be great, remember I'm new to these guys. Also i have a fluval 405, emperor 400 HOB filter and a powerhead rated at 400 GPH. Is this overkill on filtration/water movement, or should i get something else to strap on to add more movement? Thanks for the help!
