Maroons are agressive lil sh*ts and need a tank of 30 gallons per fish (they grow around 7"),Percs or Ocellaris all the way,Ocellaris IMO look alot better to,more even coloration,friendlier in general and more active fish.
Ive had both and i would never choose a overpriced wild Perc over a Tank Bred prettier Ocellaris...its the price tag that puts people off,bare in mind when these fish were first introduced they were the same price...until they were commonly tank bred,anhd the black variety is nearly double the price of Perculas.
Plus to an outsider...noone can tell the diffrence.
