I found one of my Narrow-Wedge Rasbora bleeding and swimming upside down tonight... I have him in a floating isolation chamber at the moment and he's laying on his back right now. I think it would take a miracle for him to survive at this point, so I'm just trying to figure out what happened... I've listed the likely culprits from my stock list below...
1 male King betta (4" or so) - one of the originals in the tank, has been full grown for a while and always been super mellow and never even flared at the rasboras and tetras
4 Trichogaster trichopterus gourami (4" or so, 1 male, 3 females, various color morphs)
1 Pearl gourami (4") - not sure gender... male maybe, has some red on the throat, but not as bright as the pics I've seen of males
1 Red Tail Black Shark juvie (3") - always seems oblivious to the other tank mates
The gourami were added about a week ago and I have been watching them closely. They chase each other on occasion, but nothing serious. None of them have shown any interest whatsoever in the rasboras before now, and the previous inhabitants had been getting along peachy for months. The betta doesn't even bother the gourami or even the male guppies that are also in the tank. He flares at the gourami occasionally, but never chases them or bites at them. Just puts on a show and follows them slowly (like Pepe le Pew ) until they leave his area.
Any ideas? Is this a fluke accident, or something more serious? My current guess is that the rasbora got in the middle of one of the periodic gourami turf chases, but the rasbora looks way too beaten up for that... If I have to I'd rather take back the rest of the rasbora school than any of the ones on the list above, even though I've had the rasboras for ages.
Edit: The tank is a 75 gallon heavily planted community tank that gets 50% water changes weekly.
