oh i saw them a couple of weeks ago, was they at the end of the 2nd, or maybe 3rd isle on the right?
how much was they about £25?? can't remember.
they did look skinny but they all do at that size from what i've seen, you'll soon fatten it up though!
mine is well greedy! it loves lance fish and cockles, but i feed it big crickets a few times a week and it absolutely loves them! you should get some, start with the small crickets, they will be small enough for it and it'll love them, its natural for them to get insects from the waters surface, good for them!!
