I have a 40b with 2 female mulris and was wanting to get rid of the tank after their gone to replace the carpet in that room but one of my dogs recently got her tags stuck to the carpet and unraveled a good size section which is fast tracking the carpet. I have a heavily planted 36 with an angel fish , 10ish von rios and around 6 cories. Both tanks are on my tap water so water conditions should be the same. Does anyone think the shellies would cause to much trouble in the 36?
