where to start i was planning on getting a new tank in a couple of months but have just got one on ebay for a silly price . its 48"l x 15d x18h 210L. i have done some reading on keeping malawi cichlids and was planning to use a special african substrate with lava rock and a big piece of real coral that i found in the loft. as for filters im not sure as what to get or how the flow should be in the tank. fish will be following in about 4 weeks after tanks matured so not an issue yet. does this sound about right and any suggestion about filter.
