Shrimp without airstone or sponge filter
I'm treating ich on my tetras in a separate tank using my lone sponge filter.
I'm getting a new sponge filter in 5 days.
My tank is a 20 gallon long with quite a few plants and temp would hover around 65 degrees. Couple of snails and that's it.
Do I need to throw in an airstone or should they be ok for the next week?
