I had a half blind st years ago & I kept him by himself in a 90gal & he smashed feeders even though he was stuck in the upper corner of the tank all day..i think he got them mostly at night..but again, he was half blind (equally half blind out of both eyes) so he wasn't a complete vegatable...this is different, very different for sure..when I put him in my big tank, again he just sat in the upper corner at all times..he eventually learned to take floating fd krill & sometimes canadian nightcrawlers when I wiggled them in his face, but then his growth slowed dramatically compared to the gutloaded feeders..old member (sticky rice) ended up taking him off my hands at around 13inch but wow, what a challenge..this will prob be a totally different animal being totally blind..lookn forward to updates!
