| 21 | richb since 2012-01-20 to 2014-03-18, that's 2 years, 1 months; who writes, "I purchased 1 specimen and was very happy with it. So, I purchased 3 more. All had ich. I treated aggressively and still lost one. Very asocial. All three are still on live shiners. I love the way they tripod on the tail and ventral fins. Lost 2 of them to contaminated feeders. The 3rd finally switched to thawed frozen fish (took 14 months) and is doing very well. I don't think I would buy small ones again. I would spend more and get established fish that are already eating food that is not alive." |
