I collected about 2 dozen Hyalella azteca from a wild source and placed them in a small 2 gallon aquarium I have. There are also PK grass shrimp in the aquarium and lesser killifish.
Surprisingly, I find the scuds and grass shrimp in particular to be very interesting to watch. Anyways, The aquarium has an external box filter that hangs off the back of the aquarium. The scuds are so numerous that when I am changing the filter media, I simply pull the filter out and bang into a bucket. Literally hundreds of the scuds pop off. If I need more, I can use a small aquarium net and run it through the java moss and obtain more.
I have to do that every so often or the scuds become too abundant. Substrate of the aquarium is sand, with a few larger rocks covered with java moss. I feed ground up goldfish flakes to them once a day. Water changes with distilled water once a week, 10-20%. I have been able to take the over abundant scuds and transfer them to several other ponds in hopes they will take hold. Between the scuds and young least killifish, I have an excellent feeder supply for some of the projects I am working on. I just got my grass shrimp to successfully reproduce for the first time too. I am thinking of making a 10 gallon tank in this combination to increase the numbers I can produce.
