ok well, let me start off by saying this is a temporary hold for a 4 inch oscar, a 3 inch eye biter, a 4 inch albino cat, some kind of yellow colored pleco that is about 3 inch, and a out cast convict that the other convicts beat up. I am getting a 75 gall or larger tank in the next few weeks, ( thank goodness for tax returns!) where the oscar will go with the cat, and possibly the pleco. i am thinking of turnign the 55 in to a african cichlid tank. kinda like breeding stock just like the convicts. any way, is a gravelless tank better? or is gravel prefered? i do like lots of assortment in plastic plants. in either tank. i am just wondering. and i dont need any one yelling at me telling me that the tank aint big enough for the fish ect ect, cuz as i said they are moving to a bigger tank here soon. and all that i just need advice on a african tank setup, and graveless VS gravel
