Well, yesterday I purchased a nurse shark pup from a local store which was approximately 16". Anyways because my tank was new the owner (who is a great guy) said he would hold onto it for another 6 weeks so my tank could properly cycle. Well after reading through here I totally freaked and went in today and told him I didn't feel comfortable taking it and he said that was ok, but of course was disappointed. I feel really bad going back on my word in a sense, especially since the owner has been great to work with and seems to really care about sea life (he has worked with enviromental clean ups, etc.). Did I freak too early? Should I have kept the shark? (the owner said he would take it back in a few years when it outgrew my tank.) Anyways did I make the right decision or am I just being a tard?
