ok... this day is just plain weird.

no yea... i got the decorating part.. its a normal behavior but.. i meant the agressiveness towards my dragon gobie?

he just plain hates him..when ever he gets close he opens his mouth as big as he can.. then he "stands" up right and then darts against him. but my dragon gobie is to fast (kind of) for him and moves away..

this has happened more than 4 times already..

something i found funny is that he is also very stubborn.. there is a shell he "wants" to put in his cave.. but its to heavy for him.. so he just pulls and pulls and pulls and nothing.. and then he gives up only to come back again 1 minute later and do the same..

 

........

 

so are you trying to find out why your two gobies are fighting now?

 

Eh some fish just hate other fish of the same body type for example my jawfish hates my lawnmower blenny He watches her and will attack if she gets to close though blenny seems to kick his butt lol
