Who Gives A Fish Forums

Another thing to consider is substrate. If you've got sharp gravel, it can wear down their barbels over time. Sand is ideal, but smooth rounded gravel works too. Healthy barbels mean better foraging and happier corys.

Agree with stormer99 on the Hikari wafers. They're a solid choice. I also supplement with live blackworms occasionally. My corys are super active and their colors really pop since I started this routine. Just be careful with live food to avoid introducing parasites.
