Alright, this is my first time owning a tsn, and have a few questions. I picked him up after reading an online ad. He is about 3" and cost me $3. The guy had him in a 5g community tank and complained that the tsn was eating all of his neon tetras (lol). Anyways, he is pretty underfed, but looks great regardless. He is currently in my 29g long being fattened up. He will then move to my 75g long, and finally to my 300g pond. His final home will hopefully be a soon to be made 2K gallon pond. My question is, at what sizes should I upgrade him to the next tank? Thanks MFK
