ich questions at hospital tank

[agent77]

is there any traps you could buy that will catch fish for you . I am doing the same thing and I have 2 watchman gobies I cant catch . They live under a rock thats at the bottom of 160lbs of LR . How to catch them I do not know . Everyone else was easy , but these two run anytime you go near them with the net and at night they close in there hole so ya any ideas is worth a try . I dont want to take my rock work out , it took days to put together .
