I have a 55g with a 5" Oscar, lots of snails, and 10 loaches. He leaves the loaches alone, never messes with them. The tank has lots of driftwood, rocks, and plants.
I'm looking to add little things in there. I have a never ending snail population, so I do not mind that my oscar eats them every now and then. Even when I think he ate them all, I find about 15 of them the next day.
I was thinking something along the lines of Crayfish. I know the oscar would eat them if given the chance, but if they had lots of hiding places do you think it's be okay?
Are there any other little creatures anyone had in mind besides Snails, Crayfish, and Loaches?
