I have a 55 gallon that I share with my brother. I believe that it is overstocked. My brother just added a nice 6-7'' austr. red rainbow fish. It has 1 id shark at about 4-6'', 1 delhezi bichir 5-6'', 1 fire eel 10-11'', 7 silverdollars between 3-7'', 1 small oscar, and the rainbow. How can I slim it out leaving the eel, bichir, sds, and rainbow?? I am going to get rid of the id shark, oscar, and how many sds should I get rid of. I am going to upgrade to a 75-90 gallon soon hopefully around Dec.10- Jan 11.
