Yesterday I notices two of the tiger barbs weren't looking to up to snuff and today I confirmed they have a fungal thing going on around their mouth (cotton mouth). I was mad and called petsmart. They told me to bring in the sick ones and they'll exchange them for healthy guys. So I did and I took your guy's advices and got a few more barbs, my school is up to 8 now. They were out of hatchet fish so until next time on those guys. I also really liked the way my neon's were doing so I grabbed 3 more of those as well. My rasboras and black neons are still schooling together so they themselves make a school of 10.
Feel free to message me any questions, I'll try to help the best I can!
