My GBTA has been in the same spot since I got him about 7 months ago. Just yesterday he pulled up house and started to travel. I was feeling good about him staying put for so long that I was taken back a bit when I noticed him moving. So far he's only gone about 6 inches to the right of his long time home but I'm afraid he may keep going and take out whatever he crosses. I used to feed him about 1-2 times a week with silversides and krill but for the past 2 months I've only fed him about 2 times, since I was reading that it would be OK to feed less frequently. I know it's impossible to tell for sure, but do you think that the drop in feedings has put him on the move for more food? FYI - 20 gallon tank with 130W PC lighting.
