Recently got some primo gulfliverock and live sand and have been finding all sort of interesting hitchhikers. Rocks have been sitting in the tank for about 5 days and just found this on the back glass this morning. Slug, cucumber, any ideas?
I thought cucumbers were sand sifters so finding it on the glass was weird. But after reading more comments on cucumbers in different threads, they sometimes climb glass if there is not enough food in the sand bed, or maybe a filter feeder? Dose phyto? Either way, not sure my tank can support a it.
