    Do dwarf crayfish like to dig or burrow? I currently have fluval stratum in my tank. Would sand be a better substrate for dwarf crays? I don’t mind changing it out, but id rather do so before i get any.

    I used a mix of small gravel and sand, the crayfish didn't dig but sought after already made caves and such.

    I have CPOs in a tank with both sand and Flourite, they don't seem to have a preference.

    Sand is best for several reasons but the main ones are increased surface area which allows for more beneficial bacteria to grow, sand is easier to move on and dwarf crayfish like to burrow under rocks and decor so sand is easier for them to push around. Also with sand as opposed to pea stone the babies won’t get trapped in between the substrate. But it’s not a big deal really my crayfish just seem to prefer sand.
