Thanks for your help guys.
Here in NZ, the price of imported fish skyrockets as the supplier has to quarantine them for 6 weeks. their price will also have to cover any losses (usually about 50% i think) the benifits are we only get healthy fish

We are paying up to $180 for gold nugget pl*cos and zebra pl*cos can sell for $250+
I'm pretty sure they only have brown eyes. I have seen them at the lfs for several weeks and always thought they were nice. I'm setting up the 50g with some of the more rearer fish availible and i'm hoping i will have a 6' tank in a few years.
Do you think one of these will go in a 50g and be happy. I have plenty of filteration on the tank.
So fan my list of inhabatants is:
gold batik eel
rainbow shark.
I'm also considering putting a eel-tailed banjo catfish in there.
what do you think??
