Growing Scuds

      I purchased some scuds, probably Hyalella azteca, from John Clairmont a couple of years ago.  They went into a ten gallon tank on a bottom row, and were mostly forgotten. Sometime later, when a tank was needed for a purchase of Red Cherry shrimp, I saw no reason to continue wasting a tank on the scuds, so in went the shrimp. They have been coexisting quite well, with increasing populations of both invertebrates. And the tank is pleasingly clean versus my other tanks. Having read that scuds eat both hair algae and black beard algae, I added ten each to two quart containers with black algae problems.

      Probably 15 smaller scuds were added to this 15 gallon that contains a trio of Red Cherry shrimp. The hair algae is thick on the left side of this tank. Obviously the cherry shrimp don't eat it. It will be nice if the scuds clean it up.
