They swim slightly tilted, they are easy to keep and easy to breed the stats on the right has given me a lot of fry. they look great in all kinds of tank, but my favorite is the dark tanks and the gold stone/rocks accessories. Seems very classy for a very classy looking fish!

I originally bought these as part of the "Green" series from Japan, but we did buy them separately at www.aquazone.com. If we were looking for the Japanese Green Series we found them at www.himeya.com either way they will add a bit of sparkle to your tanks.
