we have a 75 gallon tank at home and we have jack dempseys and convicts, catfish and a pair of orange (convict and red devil mix?) and a yellow and black striped bandit, a green terror and a jewel. my question is do these fish prefer just logs and rocks or plants and logs? to me all those fake plants look, well fake. we have all these beautiful LIVE fish and it just cheapens the look with all these plants in the tank. we were pricing real plants and they were just way out of our budget. we have two large logs and a few rocks where they can hide but are the plants really necessary?
