I have a Texas gowout about the size of yours in a 29 gal tank.
I have had him/her about three weeks and it doesn't seem to be growing very fast.
Do you have any idea how fast they grow?
Any recommendations on food, water temp, tank size?
I keep the tank at 82 degrees. Feed blood worms, Hikari Bio-gold and Tubifex worms. These are my first texas in quite awhile. So I can't tell you much more.
