:?: need your advice on setting up new tank of cichlids

[joshheath]

I just recently got into fishkeeping and have experimented for awhile with my 10 gallon tank. I'm now purchasing a 55gallon tank that I intend to fill with cichlids. Right now I have two very young Melanochromis Johannis that will be going in there with some other cichlids I'll be recieving for free.
-WHAT I NEED TO KNOW:::::
-What (if it matters exactly) type of gravel is recommended?
-What temperature should I keep the tank at?
-Should I bother changing my pH levels?(I've been told no, because the place I get the fish from doesn't)
-Will my royal pleco be ok in there?
And anything else you can tell me since I know practically nothing.

Thanks everyone.

Melanochromis Johannis is one of the Mbuna species out of Lake Malawi. Ideally, u should get other rock dwelling Mbuna species in your tank. They're rather active and boisterous fish. Give plenty or rock/cave cover in the tank setup.
Ideally, the pH should be high (8-8.5ph) as these fish come from very hard water lakes. This can be achieved with crushed coral gravel, shell grit or crushed marble chips.

Ur royal pleco would do much better in soft water, so I'd advice against putting the 2 together.
