After buying some live rock, I got a nasty shock. What's this in my tank? the next day it moved from its current hiding spot to another place in the aquarium. Still creepy! Please help me identify this, guys... Thanks a lot!!

Thank you so much for replying guys! I will do as you say and find a new home for my naso tang. I'll hopefully trade it in for some store credits at a LFS.

Thank you all so much for your advice! I think I"ll wait it out.. the tang seems to be doing well though.. It'd be a real pity to remove it... 1 more damsel has lost his/her life today, but the grass coral has come out of its skin and the corals are now bigger than ever. Maybe I should let the tank mature first? I've removed the triggerfish and am planning to return it to AM though. Should I remove the naso tang? What fish varieties would you recommend for my 14G tank?

Hi! I recently on Saturday, converted my freshwater tank (around 14G) into homemade saltwater using tapwater and sea salt, and put 8kg of live rock into it. However, i did not fully cycle my tank, as I only started the skimmer and the filter pump and on Sunday went to purchase a soft coral, a triggerfish and an emperor. On monday, the emperor died, but the coral and trigger fish seemed to be doing well. On Tuesday, I went to the LFS Aquamarin and bought 6 damsels, 1 naso tang, 1 brown gobi and 2 small saltwater crabs along with 2 polyp corals and a grass coral. Today, I read up about the nitrogen cycle and realised I did not cycle my tank before putting livestock in! Cycling with live rock should take a few weeks right? So what do I do? 1 damsel and the gobi has already died , although the corals seem to be doing very well . Salinity is at 31-30, specific gravity 10.23, pH is at 8.5 However my nitrite level is at 3ppm or such as seen from my nitrite testing kit. What should I do next? Any help or advice would be greatly appreciated, as I am very nervous and worried about the lives of my fish. Thank you so much for reading!
