Ive never had a tsn break its nose in 8yrs of keeping them. Broken noses are from cramming them in small tanks when there 2' imo...currently have 8 in the 24-36"range and there very placid but also in a 1700 pool....most of them were in a 650gal for a while with no problems either. Alot of tsn have "spoonbill" deformities from birth if thats what your referring too. This is from being captive bred as ive seen and own a few like this. Some are completly hanous in the head area lol, i have one with the face of camel joe and its not a broken nose as he was this way from 3" and the deformities grow with the fish. Same as deformed redtails and deformed rtcxtsn....any "chain" petstore carries alot of deformed cats in the tsn rtc families. My suggestion is a 8x3 footprint once they hit 14-18", this is a bare minium, they just need space. Ive never had any freak out or panic under high light inside a tank. Imo they also do well in numbers or a pack, they become very very calm with friends of their own kind. Guys do not flame me for saying this but a 180, standard 300, standard 265, or anything with a 2' floor depth is just too small for them. I dont even like keeping 12" ers in a 2' footprint as its just not made for them. They grow out very well in a 300 rubbermaid and the growth rate of my own from a 650 to 1700 pool was night and day...were talking packing on another 6-12" in a few weeks in the 1700 after being dropped in as opposed to being stopped at 24" even in a 9'x4' 650. If i was put in a small room permenatly id bash my head against the wall repediatly until i felt better too lol...
