I posted under “what is this fish” but now that I know what it is (there was a mixup at the store) it lead me to more questions so I’m posting here/again. I have 2 ten gallon tanks. One is my sons and the other is new. Long story short, can I put two gouramis together even if one is larger (older) than the other? They would live with a smallish plecco (I know not ideal but my son is very attached and we’ve had this plecco for awhile.) would that max out the tank or is there anything else that can be added? I don’t want to over populate the tank but I don’t want it to be too empty either. The plecco is very aggressive (which is why I moved him to the new tank) but he seems to do okay with the gourami.
