With my tax return my husband is letting me buy a new tank 250gal. I am going to move my violet goby in there. as well as some live plants. wondering if anyone had any suggestions as to what else would be nice in there. I am debating between adding several small schooling fish or finding one more large fish. the goby is currently about 14inches long and housed in a 160gal tank. almost a 100% freshwater. about every other month I add a gallon or so of salt water(slowly) and then it receeds back to fresh with my water changes. any suggestions would be great Thank you!
