i be reading and you can keep small tankmates with oscars, but you put the small tankmate in the tank first , then the oscar. i migth buy a litlte pleco or loach or something like that, what stay small and clean the tank .
have anybody keep a weather loach with a oscar. becasue if i get one i could but with my weather loach in the tank , with a juvenile oscar , so the weather loach will help to clean the tank, and the oscar could be less agressive when it grow up. so when the oscar grows i will put the weather loach back in his tank . and probaly the loach will be bigger then 12cm or bigger when i get a ocsar and tank. do you think this is a good idea.
