the gudgeon is about 5'' or so and very healthy and the puffer is in great health as well and they are both in community tanks and have been for quite a while(2years give or take). we are just wanting to make room for some other fish. we are looking for maybe a jardini,red tail cat,ornate, dilheazie,albino or any nice bichir,flagtail prochilodus,or even an atlantic stingray(small). if the deals are worth it I will add money so dont be afraid to throw out an offer. here are a couple pics too. thanks
