Been thinkin bout a leaf fish. i know they eat basicaly only live fish so i was thinkin... plant a 30g put some guppies in there and let them spawn a few times and some ghost shrimp or somethin... then get a leaf fish as sort of population control cause i dnt think he will be able to clean out a 30 full of fish that spawn like crazy... idk i think thated be really cool it would almost be self sustaining only i would have to feed the guppies obviously but idk about to much about leaf fish but i thought it was a good idea... what yall think.
