I have 9 clown loaches. Six of which are at least 20 yrs old. I was thinking of finding a good home for them. I'm willing to sell them to someone I know can take good care of them. They're in a 125 gallon river tank. They're in very good shape and very healthy. This is going to be a difficult undertaking on my part because I am very attached to my clowns. How do I go about finding a dedicated and committed person that can take good care of them?
