agressive upside down

[SANND]

Hey ya'll,

My biggest catfish has become very agressive lately. He/she chases the other two away when they're all trying to hang out under the fluval and sometimes if the other two are hiding in their peice of wood, he/she goes in and flushes them out. Last week I saw it 'wrasslin' with the smallest one.

Everywhere I"ve read has said they're very peaceful tho. Has anyone else had a grumpy upside down cat before?

I never heard of agressive dwarf upside down cat but one thing comes to mind that they belong to Synodontis family and there are lots of oddball among them. I'v read that they do not like each other too much and can TRY to bully other fish (mine S eupterus in cichlid tank does).
In San Diego water world fresh aquarium i saw LOTS of these dwarf cats together in a tank - they were hanging upside down here and there each minding its own buisness - dif to imagine themto be aggressive.
