You may all have read about my problems when the African tank filter was accidentally unplugged while we were away, well...
Went away for the weekend. Came home, fed fish and moticed 1 dead male rosy barb. Didn't seem to have been dead long, still whole, full colours, eyes still intact etc. Couldn't see anything wrong with him but removed him from the tank then went to bed.
Today I was very busy and didn't go near the tank until I sat down for a quick lunch before heading to an appointment. Glanced over to the lounge community tank and thought " Funny, why are all those fish at the surface?"
Go and check. Uh oh, dead bodies everywhere!
Hmm, rest at surface, gasping - lack of oxygen. Why?
Check water temperature - it is 34C. Oops.
Obviously faulty thermostat on heatpad (which has been running over 10 years without a problem until now). :evil:
Unplugged heatpad.
Hauled out dead bodies - 2 giant danios, 11 rosy barbs, 1 angel, 1 bristlenose and 1 Chinese algae eater.
All the gouramis look happy enough :roll:
Then I added an airstone to increase oxygen levels and did a 50% water change to bring the temp down to 27C.
Now, I know you are supposed to alter temperatures slowly but in this case it was necessary. Besides, my Africans get big temp fluctuations when I clean out their tank and they love it.
Hard to tell what is left as they are all hiding after I rummaged round the heavily planted tank looking for more trapped dead bodies.
The rosys were hit hardest as they prefer cooler temps anyway.
Sorry Jude, not sure if there are enough left to breed this summer.
Will watch over the rest of the day and wait until the survivors venture out to see who is left. Poor fish did not deserve to die like this.
