Urgent Long nose butterfly help

Unfortunately you really have to take LFS advice on stocking with a grain of salt unless otherwise known. It is a business, and that is good, but you really have to be cautious regarding what is appropriate for your tank.
Forums usually have a wealth of information available from hobbyist that have been doing this everyday for years. The advice that you garner here will assist you in making the best choice with the information you have available.

MoJoe is right the tank is too small and the stress may lead to disease or aggression.

Hope your fish pulls though.

 

I def agree that tank is much to small to house a longnose butterfly. Most lfs will tell their buyers anything to sell a fish. Is there a chance you can take it back for a smaller sized fish? If you go to Aquarium Fish: Tropical Freshwater Fish and Saltwater Fish for Home Aquariums they have a great nano section where you can find some great fish that fit perfect in a 30 gal.

 

Thanks--I may look into that. I have a feeling that they will not take the fish back because it's been in my tank. They could just say that they don't want to run the risk of adding the fish in to their system. I wouldn't mind trading the butterfly in for a midas blenny (don't know if he would be OK with a scooter blenny though).
