    Hey guys,

    So recently I decided to add 10 Rummy Nose Tetra (RNT for the rest of this post) to my 29 gallon tank, with heater, plants, established cycle, etc. For the first 2-3 days, the fish got along fine, all were swimming actively and eating well, schooling together etc. Then 2 days ago, I woke up and found one of the RNT dead on some java moss. Since they were new and I didn't get to observe them for long, I decided to throw this one to a human error, maybe not properly acclimating, etc. Then, last night before I went to bed, I saw a particularly skinny RNT swimming by itself, getting pushed by the HOB filter when it swam under. It wasn't schooling with the others, so I was worried. 1 hour later, it was dead on the floor. I started to research different diseases and illnesses, but other than being on the skinnier side, nothing gave way that it was sick physically. I was down to 8, though I did a thorough check last night to make sure the other 8 were swimming and schooling healthily (which they were). This morning, I found another RNT swimming alone in a corner, breathing more rapidly then others, also appearing skinnier than the others, but I got a picture or two on its body and found something I didn't see or catch yesterday. Anyone know what is going on?

    My guess is Hemorrhagic Septicemia. That would account for the red blotches on the head & body. IMO, the HS symptoms were likely caused by a bacterial infection.
    Probably a good idea to remove any fish showing symptoms asap. You can try medicating with antibiotics, but once infected recovery is unlikely. The stronger Rummies might survive.

    I thought so too, but would bacterial infection be the only cause? I have a betta and a gourami in there (I know it was ill advised, but everyone in the tank gets along with the occasional chasing), and I'm worried that they somehow focus on a single RNT? I just want to know if there is a possibility, since maybe some sort of bullying or aggression is causing the predators to attack the RNT.
