The puffer is a white spotted puffer, there are pictures of him in the Giant puffer section when he was a bit smaller, he only shows his true colours when the lights go out, most of the time is quite dark and sedate
Gobies can be buggers for digging things up, we had a yellow headed sleeper goby once but he jumped into the overflow

we've since changed it so it cannot happen again.
Gutted about that because he was such a perfect little chap and no one bothered him, which i have to be careful about at my female devil damsel doesn't tend to like gobies which restricts us to what we can have.
My eel goby spends its life under the rocks with just his head poking out, he's made a network of tunnels under all of the rock, great little chap, i wish i'd got another when they were available, i think hes about 5-6inches long now and very fat! lol
The tank is a 149 gallon aquarium, we're hoping to upgrade when we move house, which we're hoping will be in the next 12 months, if we do though, then we're going monster-tank, looking at a 8 or 10 footer!!! that will be fun and very exciting if we do, that will be a main aquarium and we'll obviously have some smaller ones for the other puffers and my partner wants to keep more shrimp too, hes a bit of a amrine fish fanatic and of course everything has to be bigger and better with men, haha!
