Hey all, I have a water feature in my terribilis tank that I would love to add fish too . The "pond" holds about a 1/2 gal of water and has a stream flowing into it . It has no external filter just cycles through so waist would also be a factor ? Though it dose "filter" through lots of gravel . Also have some top water "lilly" that I woulden't like the fish to munch too bad .Lots of sprintails on water surface also possible food source for fish ?Sorry this sounds alot like a beginner topic ,I just really do not know a damn thing about fish except how to catch them ! Ideas welcome .
