I have been trying to think of a way to rid my tank of a Goby shrimp. He is diggin tunnels all the way down to my plenum and I am scared he will ruin the denitrification. He always stays in his tunnels and I can't think of any way to trap him I have three other shrimp in the tank and I fear I will only end up trapping these guys with whatever i come up with. Any suggestions
