I've decided that the Scarlet Badis I was planning for might not do well after all. This will have RCS and this is to be a self sustaining tank which means no water changes or feeding the fish. The plants will serve as filtration. The RCS is to serve as food for the fish. I already have plans for a 6.3 shrimp tank to keep a shrimp colony in case the colony in the ten gallon is almost gone. I'll be using the Walstad Method to help me make the self sustaining tank. All I need is another species put into the tank that will eat the shrimp and or the shrimplets. They have plants to graze on as well.
