Question
Hello,
His eyes are a little foggy wondering if it is his diet. Also i'm thinking of buying a plecostomus wondering if they will fight.
   Thank you.

Answer
Hello,
First of all, Oscars and Plecos do extremely well together. Probably the most frequently paired fish if I had to guess. Go for it!
Foggy eyes are usually a sign of poor water quality, which is completely inevitable with fish as messy as oscars. Check your concentrations of nitrogenous aqueous ions. If anything other than NO3- are high, that will help explain the problem. Until then, make sure the tank is in the high 70s- low 80s temp range, heavily aerated, and try a partial water change with a gravel vacuum. Let me know if you need clarification or anything else.

Expertise

I can answer questions relating to the scientific aspect of the hobby (fish ecology, biology, genetics, etc. ), aquacultural and breeding aspects, and have experience with nearly all "brackish" fish in the trade. I also have lots of experience breeding fish, like angelfish, tetras, cichlids, and various livebearers. I also have lots of experience with many freshwater fish, especially "monster" fish, like stingrays, arowana and Saratoga, cichlids, catfish, etc. Please ask questions about anything except for true saltwater (reef) tanks.

Experience

Too much to fully list, but I will never have never enough to satisfy myself.
