My clown loaches are in a 90 gallon because I am following the advice that is recommended method of raising them from the great people at
www.loaches.com. Recommended care for the clown loach can be found here:

There is no need to make a personal attack; I never said that clown loaches could not be kept in 130 gallon aquarium;
I said that they could not be housed long term with an oscar and other fish. Size is not the only issue; between the loaches and the oscar enough waste will be produced that 130 aquarium will not support the bio-load of these fish long term. Adding more fish will only result in the need to upgrade sooner. I understand the needs of my loaches and have both the commitment and the resources to upgrade as soon as is necessary. This is not the case for everyone so I just wanted to make sure that the original poster knowns what will need to be done.
