Oh I totally forgot about the goby family thing :| But I really don't like YWG since they are just, STILLLLLLLLLLL! Even my banggai and firefish move around the whole tank :P Weird :P |
Please save yourself the trouble and learn from other peoples mistakes, you have identified that this tank is too small & it contains goby predators.
Although I agree this hobby is about challenges and learning, its also about trying to be as environmentally responsible as possible. Put yourself in the Mandarines shoes, would you enjoy being put in an overly small tank with a lack of food and things that could kill you @ every turn?
I think not... But alas I have a feeling this fish will be added to your tank regardless.
