Ok so last night i brought a neon dotty back and introduce him properly. But that no the problem, this morning some sort of hermit crab without a shell appear. In the tank are 4 crab hermit and a clownfish here is the photo:
was it moving in the flow or by itself, count your hermits. If you have 4 still id say it is a molt, suck it out of the tank just incase, although if it is a molt as i presume it will be consumed!
haha yeah my presumption on my first hermit molt exactly. i figured a bigger hermit tore it apart and i was offended that they would do it to their brethren!
