ANGRY fish

Shekoi

Trying to start up again
i noticed a couple of days ago that there was i slight rip in the tail and part if it missing from my fancy guppy. fisrst i throught it was the angel as he is becoming very aggresvie with age, but i've only ever seen him chase the honey gourami and one of the swordtails.

but this morning i noticed that when the guppy swam into the middle part of the tank all 11 H. rasbora chased him they all surrounded him until he could get into the thick planted area. why have my fish become so angry? i've never noticed anything like it before.

what should i do???
 
Looks like it's pretty packed in there. It could be a space issue if the angel or gouramis are involved in any 'angry' (territorial) behaviour. With the rasboras, that's kind of what they do - schooling fish have a pecking order, and will pick on lower fish or other fish in the tank. They're not 'mad' at your guppy, they're just doing what comes naturally and putting him in his place.
Honestly the best thing to do is get a larger tank so everyone can spread out and feel less crowded.
