Snails/Crabs

[cwop357]

I have 26 gallon aquarium and I only have 3 snails and about 4 hermits. How much should I get to have an effective clean up crew.

Am certain others are going to tell you that you need much more.

But I don't have many more then that in my 125 gallon.

Question is, are they doing the job for you? Keeping most of nuisance algae off glass and keeping sand and rock cleaned up.

If not, you need a few more of each.
