Sadly, I decided to remove my BP. I watched the tank for a while today, and my Oscar just won't leave my BP alone. I took my BP back to my LFS (which happens to be a good one) and I ended up getting a 5-6" Jack dempsey. I was expecting all heck to break loose when I put the Jack in the tank (especially since my Oscar hasn't had any cichlids in the tank except the BP which he grew up with). But to my suprise, nothing happened. I put a lot of pellets in the tank right before I put in the JD in hopes of distracting my Oscar. To my suprise, the JD swam right out of the net and started eating all of the pellets. My Oscar has given him a bit of a chase here and there, but he is a much much better swimmer than my BP, and easily avoids my Oscar. As far as the pleco is concerned, the JD took a peek at my pleco, and the pleco came shooting out of his hiding hole and smacked the JD in the face. I guess that took care of that. I am keeping my fingers crossed. Hopefully they will be ok together.
I am very diligent about my tank upkeep. I will probably take the silver dollars out in time, but for now I think they are fine. I think that with my tank upkeep and my filtration I can get away with the one Oscar, JD, and my Goldie pleco. Plus, my tank is a foot longer then the standard 75 gallon, so I feel that it gives the fish more room to establish territories. This is the plan, assuming that the Oscar and JD get along. If not, my Oscar will be a solo pet.
