Oops, sorry Menagerie, I didn't know about that thread.
The sick neon rosy barb is in the 75 gal
. which has been set up since July. Current residents are listed below in the sig. I got all 5 barbs at the same time, on 10/8 and moved them into the 75 gal
after quarantine, on 10/14. Everyone else in that tank has been healthy, no problems.
Did tests yesterday: ammonia 0, nitrite 0, nitrate 20, pH 7.6, water temp 80.
I do 20% water changes weekly and vacuum the gravel. Last water change was this past Friday.
Filtration: Cascade 300 and AquaClear 110 HOB
filters, for a total of 800 gph
Eheim Jager heater 250 watt.
Two air stones.
Nothing new has been added to the tank since they went in.
Largest fish is about 4 inches (pictus cats).
I'll repeat his symptoms: lump behind the gill opening, right side, both eyes bulging a little bit. He's still swimming around and sometimes looks fairly normal, but other times he hangs out under a plant or near the surface and it looks like he's trying to get food. He doesn't seem to be gasping for air.
