One more question, haha, I`ve been told that the internal filter won`t be up to the job (due to the amount of fish). Would I need something as big as a Fluval 404 which I use on my other tank....or would the next size down suffice? Thanks peeps.
If you decided to go with mbuna you'll be overstocking to keep aggression down so you'll want a minimum turnover of 8 - 10 times per hour. If you decide to go with peacocks or other small haps you won't be stocking as heavily and can get away with 6 - 8 times per hour. Though you can always add more movement with powerheads if you like as long as none of the fish are getting blown around the tank.
