Just wondering if there is a different, maybe better, type of food to use for my corries and kuhlis? Right now I'm using Hikari tropical sinking wafers. I don't have problems with it but it is very old lol. I'm just considering a change since I'm almost out of the wafers and maybe there is something out there that is better. I saw some sinking shrimp pellets for bottom feeders but I have a feeling it will never reach the bottom or it is too small to be noticed in a 55g. Thanks in advance.
