I recently introduced an indo dat to my tank about a month ago, seems to be healthy, eats like a pig, and gets along with my AT dat and gar just fine. Most of the time, it hangs out by my large piece of driftwood, and turns almost the exact same color as the wood. For short periods during the day, and when feeding, it regains its stripes, but then goes back to stealth mode. I have lots of caves and hiding places for the fish to go, but the indo seems a little stressed out. I know many dats change color to blend into surroundings, but if its stressed, I'd like to help it out. Anyone know if this behavior seems normal?
