Gouramis picking on other fish

Hi all,

I have a community type tank. I have 3 small Angel fish with the intention of placing them in another tank in the future. I also have 2 x 3 spot Gouramis, 2 x Cobalt blue Gourami, a handful of guppies (overflow from another tank), some mollies, and albino corydoras.

Now I've noticed some of my Corys are missing the majority of their tail fins, Some guppies now have split tails, a couple of my mollies have died. The only act of aggression I can see is from one of the 3 spot gouramis, but mostly it chases the other 3 spot around the tank.

Would this goruami likely be the cause of my problem? I'm considering rehoming him on his own to a friends tank. Should I rehome the other 3 spot while I'm at it?

What size tank is it?

Yes I would most certainly look at the gouramis as culprits.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

The blue gouramis - are they dwarf gouramis or 3 spots?

The cobalt blues are considerably smaller than the 3 spots. the 3 spots seem to be the bullies atm.

Yeah they can be bullies alright. I would see if removing the one that's being aggressive doesn't fix the problem before worrying about the second one.
