Should've first researched him before taking him and here I am now all wet just trying to catch him in my 210 gallon tank, it's been about a year having him and I didn't have any problems until I thought of adding some nasarrius snails which i had caught from the beach (he wrecked absolute havoc on them) so much so that those snails were just too stressed to even come out of the shell since then I've been trying to catch this little rat but to no avail, i had taken the advice of waiting for him to sleep and then catch him (it would've probably worked in a smaller aquarium but to no avail in my 210g with my Tess staring at my fingers at all times)
