Hey guys/gals,
I'm new here, and I'm hoping my problem has subsided, but just curious as what might've been causing this. Let me describe my tank first, i've got a 55 gal tank, it's freshwater, with a gravel substrate and fake plants for decoration/hiding spots.
my fish:
2 bala sharks
7 tiger barbs
3 zebra danios
3 rosey barbs
So everything was going well, and I found a couple more fish that I wanted, I picked up 6 green tiger barbs and my girlfriend wanted a couple mollies, so we bring these fish home, and float them for 20 minutes or so, and then I let them out and they all seem happy, swimming around with their own species. 2 days, everything is good.
A couple days later, i notice that one of the green tiger barbs is missing when i get home from work, and i end up finding it's corpse, which is not much more then a little meat left on a skeleton at this point. So i pull it out, and just hope that it wasn't diseased and spreading that disease to whoever ate it(I don't know if thats how it would work, but it seems logical to me).
Then the next day, i see one of my regular tiger barbs getting picked on, they have always tended to just kinda hover in the water with their head at a downward angle, but if any other fish went near them they'd zip around out of they way, and this guy was just getting picked at bite by bite... so I continued to watch hoping he'd snap out of it, but no luck, he began swimming around sideways and I had to take him out before they finished him off...
over the next few days, this continued with one more regular tiger barb, and 2 more green tiger barbs, and one of the bala sharks died too. There wasn't any discoloration or marks on the fish, no change in the water, all the readings were still good.
But it's been like 4-5 days since I've had another death, so i'm hoping it's over now, didn't know if anyone might have any ideas, or at least something I can look for if anymore happen to die.
Thanks for the help,
Derek
