they get along great just like most other bichers they are all over aech other. they have a 6' tankspace to move around in but they seem to not want to go to far away from each other.
I did notice that the smaller one ended up wtih a tear in his right perctoral the day I added the larger one but I'm not sure how it got there and it's healing well.
I can try to get pics but It won't be anything grad my camera sucks.
