I can't offer much support about the Clowns with the Oscar, my guess is Childawg is right, he'll have him for dinner. Not to mention small clown loaches just small ones are expensive fish(well i consider them expensive.. but im kind of cheap lol), would be spending a good chunk on larger ones.
I'm getting 5 clowns for my 55 that I got, I can't talk out of experience because I have none, but I can't tell you what I have learned from reading a lot about the,.
They are slow growing, in fact because of there rate of growth, most never reach sexuality maturity in aquaria, which is why they have rarely spawned in captivity. They can live 10-20 years, possibly longer, pending on where you read.
I thought it was also intriguing how the just lay on there sides at the bottom of an aquarium to rest, usual frightens experienced keepers into thinking there loaches are dead.
Maybe you know some of this, but I think there awesome and I can't wait to get them. To Bad I still have to buy substrate, decor, filter, heater and few other things, and not to forgot about the cycling process.. doh. Anyways hopefully you can work something out, I think they'd be a good addition to any aquarium.. well as long as they don't get mistaken for dinner
