wierd behavior of clowns?

[harrisagogetter]

I have two false clowns which are tagging back and forth. The smaller one(which is about 1/2 the size of the bigger) keeps nipping at the larger one. I have had them for 12 months now and both seems to be fine earlier on in the week no problems.

1. If the larger one is swimming in a vertical position in the corners and in places that are more secluded what does this mean?

2. Is this natural for them to do this?

3. Is there anything special that should be done(aka quarintine(sp))?

feeding habits are ok nothing wrong with water like I said before everthing seems to be ok but this, and it is all of the sudden.

Thanks
Aaron
