Ocean Rock With A Crayfish?

[donna 123]

Ive had my crayfish a month and want to make a better home in his tank,
i have some of that cream colour ocean rock left over from when i kept cichlids, is this ok with the crayfish?

yep. Most cream/ white coloured rocks from the beach are limestone or sandstone and are fine for rift lake cichlids or marine tanks.

the rocks would be fine. a few nice caves will also go down well, indeed, are very important. gravel of less than 1/8 inch is good too. Redclaw like to dig, and burrow. finally, if you have not already done it, move the outlet to you filter up to surface level. Cray need a high O2 environment.
