Was looking to add around 10 to 12 Rummy Nose Tetra to my 29 gal. tank. It does seem like there are some people that say these are very hardy fish and others who say they are some of the most fragile fish. I just sent an email to Aqua Huna and he replied that he doesn't ship these fish out anymore because they do not ship well and he was having too many die. Let me know your opinions on this fish and if I should throw that idea out the window and search for something else.
