I'm looking to setup my first Malawi Cichlid tank.
I've had community tanks, Discus & Geophagus tanks, and am currently running a marine aquarium. The marine aquarium is fun because it's a little tricky at first, but you do end up with a small number of small fish in a tank. I'm looking forward to some larger fish (these still won't be large fish) because I saw my Discus more as pets than decorations, and I reckon my little boy (20m.o.) will love the larger fish. So I'm keen to have a crack at an all male Malawi tank.
My Dad's storing an empty tank that's roughly 150*45*50cm (~340 litres / 90 US gallons) with a few canister filters that I can use, which I thought I'd start with (I'll check their capacity first). Having some experience with them I much prefer sumps, but this tank isn't drilled and is free. I guess I could have a crack at drilling.
Anyway, my real question is that I've read some advice that I'm trying to reconcile:
Introduce all of your fish at the same time, as juveniles, to manage aggression.
For all-male tanks, add a bunch of juveniles for every single male you're trying to find, and later remove all but the most dominant male of that species.
If I did this, I'd be adding a lot of fish (they would be small at the time) at the same time. At least five times the amount that I'd end up with I think.
Can someone point me in the right direction?
