Blue Neon Gymnos come from Valentines in Uruguay, two names. . . same fish. They are a Gymnogophagus Rhabdotus type - GREAT looking fish, but, needs cool down period for a long happy life.
I wouldn't recommend them for your tank. Hrps and the compressiceps will not enjoy the cool down period and the hrps might be a little too aggressive for them as well. Gymnogeoss are awesome fish but its best to plan a tank around them.
