Hello, I am getting different opinions on whether or not it is necessary to have a bubble maker for crayfish. Some say they have successfully kept crays for a long time without air stones while others claim that without, the crays would drown. I have to say that I am quite confused now. If anyone could clarify this issue, I would greatly appreciate it.

Thanks

Assuming that the tank has proper filtration (which *all* aquatic animals need), there should be enough surface agitation from the filter flow to get oxygen into the water. However, if there is no filter of any kind (not recommended), it would be best to have an air stone to keep the water from getting stagnant and to get oxygen into the water. Air stones themselves don't put the oxygen into the water, it's the surface agitation that increases the amount of dissolved oxygen.

Have you successfully kept crays without an airstone?
