Smallest algae eating/grazing fish for 20g

[adsf430]

I have 3 turbos, 2 tiger conches, 2 emerald crabs, and at least 15 nassarius in my 20 gallon and they do a good job. Only issue sometimes is still hair algae in divets in the rocks or hard to reach places. Have never found a small enough fish worth trying.

For my 20 gallon high the CUC is five turbo snails, seven nerite snails, seven trochus snails, five cerith snails, and one nassarius snail. I have a few scarlet hermits as well. Twice a week I feed them one chopped up algae wafer and some crab cuisine onto the substrate. I only use Walmart distilled water.
