I recently visited friends in Knoxville, Tennessee and stopped by a local fish store called The Aquarium. My friends were looking for some fish to add to their tank and I was looking for loaches (of course). In a tank with Sewellia lineolata I noticed a smaller more elongated hillstream. When I finally got a good look I identified it as a Pseudogastromyzon cheni/myersi. It appears to be a young male and it made the trip home with me. At one time, I had this species spawning like crazy and had more young than I knew what to do with. Now, those are all gone and I have not seen this species in years. Now if I could only find more. In a side note, the same store had a shipment of White cheeked gobies. They told me their had been another species in that shipment that from the discription, was probably Liniparhomaloptera disparis. Unfortunately the fish was either sold or died. That's another species that I once had spawning regularly, but have not seen in years.
