I've got a 20 gallon Amano fish tank, shared with 2 Panda Garras and 2 Hillsteam Loaches. I guess I was the lucky the Hillstream Loaches are a mating pair. I now have about 20-30 babies swimming around the tank. There could be even more as I really can't count them and there all different sizes. You cant see some on the rocks and one on the moss ball.
