that could be why my Pac is so stressed, at the store he was in a tank of 90% water and had a little rock landing, i didnt want to have to go thru the trouble of keeping up with the water i.e. filtering, cleaning, etc. so he's in the total opposite now, 90% land with a water dish, im guessin its too much of a change for him. Thanx for bringin that up Grif.
