Keep your Nitrate LOW, and dissolved O2 HIGH. Lots of turnover/water flow in the tank is mandatory. When I shut off my twin sump return Mag 7's and 2 Eheims on my 180, my Tig goes nuts, he hates still water. As soon s your kick the pumps back on he's happy. DO NOT OVERFEED! Beyond that, they are pretty easy. I consider 10ppm Nitrate the absolute upper limit for my tank, and change out 40 gallons, 2 times a week, sometimes double that if the levels peg over 10. Good luck, post pics. Alot of people will tell you that Tig's swimming vertically up the glass is normal, I think that's bull****, IMO it's a sign of stress, or a lack of hiding places. You really need to have a good hiding spot for him, or at least a big stump to lay under or behind.
