Well over 24 hours later my panic is starting to go down a bit. I think everything will be alright. Despite having a nasty reputation Shredder has not shown any aggresion at all and is acting very pleco-like. I have not seen him eat driftwood but you can see the clean pingpong balls and he has been eating romain lettace, rabbit food and algae waffers (the ones that the oscar's miss).
