Who Gives A Fish Forums

I've been looking into keeping these fish and I'm a bit concerned about their care. I've come across a few articles that suggest they're quite delicate and might be more challenging to look after than malawis - has anyone had any experience with them?

Are Tanganyikan cichlids easily found in most pet stores, or would I have to search further afield?

I've had people tell me Tanganyikan cichlids can be a bit more high maintenance, compared to those from Malawi - does that hold any truth?

I'm thinking of housing cichlids in a Juwel Trigon 190 - about 45 gallons. Would it be feasible or not?
