curled mantals?

[dr.darkness]

Only 2 of my crocias mantals are curling and none of my maxima are doing that.Water params are fine and I haven't seen any thing bothering them.

how long have you had the clams that are curling? and when was the last time you added a new clam? have you changed any additives at all?tell us everything you use for filtration,dont hold back tell us every little thing. and can you post your water tests?

My crocea has cured up mantles a month ago. I have two derasa, 1 squamosa, 1 maxima, and 1 gigas together and the crocea was the only one with the curled up mantle. I did a fresh water dip and slightly switched it's position in the tank and it has recovered from the curl and resume growth since then.
