I agree that carpets when young like the rock a lot better, but when older like the sand a lot better, like you said. Thank you for the kind words. I do plan on him getting much bigger and would like to see him get to his full potential in size, but only time will tell. I plan on keeping him in there for about six months to a year depending on i much i feed him will determine that. When he is out of the tank i have some frogspawns, toadstools, hammers, that will take his place and make the tank look just as good. But not really the same, when people come over to my house and see my nano, the very first question is what the heck is that blue thing? And boy do i love to tell them, its like my buddies dont even care about my lagoon anymore, it must be because the carpet is new.
