Just thinking about maygbe adding a dwarf frog to my tank. I think having one animal other than fish to my tank. I understand they grow to an avg of around 2" - 2 1/2" so the room will be no problem. The possible problem would be that my tank has tiger barbs and a red-tailed shark. The "shark" being territorial around the bottom of the tank, will he get pissed off at the frog. Also could the barbs be a hassle for him or do you think the frog 1- could fend for himself and 2- would be left somewhat alone? Any thoughts or comments will be greatly appreciated!!
