I ended up getting lured into family stuff today and neglected Gillbert again in the process. Tomorrow and tomorrow and tomorrow... I'll clean it all out tomorrow I promise Gillbert!
The time I did spend with Gillbert today he seemed very happy and active. The water actually seems cleaner than I first thought but the tank definitely needs a thorough scrubbing. Hopefully I can get the rock and castle reasonably clean. I have a little holding tank for Gillbert but I don't want to leave him in it too long. I have no idea how long everything will take but I guess we will find out tomorrow.
