I have a 40 gallon long tank for my ever growing GABF but now for the second time the divider has broken a seal and I had major swamp on the dry side. I have a fluval 406 tank filter system and was just wondering if I can just clean out the swamp and run a 6in deep full water tank for him. I don't think he will mind because he only come to the land to eat. any thought or concerns would be great. its just getting super annoying going through this every 3 months
