I am new to aquariums. I have a 55 g well planted and many many hiding places. My wife and I have been stocking fish ourselves and have the aquarium perfect in our eyes, but after some research we have found we have fish that aren't supposed to live together... our tank has been setup and had these fish for about 4 months and everything is great.. we have 1 goldgourami, 1 blue gourami, dwarf gourami, 1 labelled goldfish, 1 pictus cat,1 sailfin cat, 1 Raphael cat, 2 tetra, peacock eel,1 goby,1 Angel fish,and two mollies and 2 cichlids.. I have a twenty gallon I can setup but not sure what to move where.
