Thanks!Yes, you can do this in a 40 breeder. I would start with at least 6. They make excellent parents and males will spawn with more than 1 female. They are not true shell dwellers like multis but females will use shells to lay their eggs. Grab some extra large escargot shells off of amazon. Sand substrate. What are you water parameters (pH & hardness)?
The 50 gallon lowboy would provide a much better footprint and more room for these fish as they hug the bottom anyway. They don't use much vertical space. Get some pieces of texas holey rock (limestone) to break up lines of sight. In my humble opinion the 50 low boy is one of the best tanks you can use for any shelldweller community. Wish I still had mine.Also I'm thinking a 50 gallon lowboy might fit them more than a 40 breeder due to the bigger ground space. Any thoughtS?
