Temperature is 26 degree Celsius.Feeding him tetrabits and algae wafers.Last time he ate was 2 days back.He moulted 3-4 weeks ago.He is walking oddly.I bought him 4 months back.
In my experience my boy goes that teddy color shortly before molting. It might’ve been a bad previous molt and he’s preparing to molt again.if your tank is well cycled I’d also recommend lowering the volume for water changes. Inverts are very susceptible to change in water parameters so he might also be stressed from that.
Does he have any caves to hide in? And do you supplement calcium?
