Hello all, I am so happy to find a fish group that seems to have so many useful ideas. I stumbled across this place late last night. I am back into the "hobby" aka "obsession" after 20 years. These days I find Zen watching my fish. I presently have a 20 gallon and a 5.5 gallon nursery/med tank. I am always wanting to learn things about fish by more experienced fish keepers. I am happy to be here.
