I came home today to find one of my Tiger Barbs floating upside down in the upper-corner of the tank behind my heater. I thought he was dead, but he was breathing pretty heavy. He almost didn't respond when I touched him with the net, but he swam, and didn't even try to get out of the net when I got him. I am getting water into a QT tank, but I need help. He looks like he was bleeding near his anal fin, and there isn't almost any skin there. He just sits in the net floating upside down in the net.
Water Params: Ammonia-0, Nitrite-0, Nitrate- >15 PPM, pH-6.9. Temperature kept at a constant 79.5 degrees.
Tank size: 30 Gallons
Live Plants: Yes
CO2 system: Not yet, but ordered. I have been adding CO2 for my plants every day till my the set-up comes in.
Tankmates: 4 other Tiger Barbs, 3 Red Wag platies, 1 Amano Shrimp.
I take it it is the Tiger Barbs. One of my barbs has constantly been chasing 2 of the barbs who don't fight back, which this one is.
I, honestly don't think he is going to make it. I need help. :(
