I currently have a 90 gallon with a couple angels, 2 clown loaches, 2 GBR, a black ghost knife, a pleco,and some platies. I would like to get some gouramis but I understand male aggresion with other males or even when breeding with females may be a problem. I would like to get multiple though, so can I get a male dwarf and some female opaline or blue regular? The tank has lots of plants and hiding spaces, but I would rather not force one to hide all the time.
