Both the tank and sharks look awesome. I noticed in both of your tanks you have little sand, why is that? Is it just the two sharks?
Thanks...and yes its just the two sharks. Years of freshwater keeping have made me hate substrate in general. 90% of my tanks are bare bottom so this is pushin it for me lol...i think its more than plenty for them. IMO deep substrate beds hold waste and can cloud the water when stirred up. I use just enough sand to get by so when the sharks move/stir it around it remains clean.
