Ok, so I was originally going to purchase a 55 gallon aquarium for mbunas, but then I saw 75 gallon price and now I'm leaning towards that instead. I have a 29 gallon that is already set up, so if I need to put any fish in a 'time-out' to mitigate aggression, I can put them in there. One at a time, or maybe with a divider to keep them separated until they're back in the 75. First question: is this a good stock list? My LFS has all of these: 1m4f Acei 1m4f Red zebra 1m4f what my LFS calls Pseudo. Deep Msobo 1 Cyno. Afra 1 OB Zebra (can I have just one of these with Red Zebras?) 1 Labidochromis Nkali (already owned, he's in my 29 gallon but has an injured tail) Pseudo Deep Msobo males look somewhat similar to male Melanochromis parallelus. Could I get both, or only one, since males look similar? Would the Red Zebras try to crossbreed with the female Msobos? I'd get more Afras but they're more expensive than the other fish at my LFS so idk. Same with OB Zebra, but the main reason I only want one is because I like the look of it, but not if there are 5 of them. Second question: if it's ok to get just one of a certain fish, should it be male or female? I'm more concerned about the well-being and peace between the cichlids than whether the male will look better than the female. Third question: what kind of filter would I need for this setup? Thanks.
