Happy new year to all
A poor start to my 250litre aquarium's new year though with a dead bristlenose cat fish... with all other fish (barbs and platys) looking extremely healthy, one of my 2 catfish first looked lethargic and 2 days later was dead on the bottom of the tank? No outward signs of disease or bloating. a water test showed ammonia, nitrite and nitrate to be 100% spot on pH was 7... We have had some hot weather lately and I did record a tank temp of 29' on a day that was 37' outside. That day I left the lights off to keep the tanks as cool as poss and turned the airstone up to max to keep oxygen levels up.
I know from articles that the bristlenose can take some time to aclimatise to a tank, but it has been happy and active for 3 months in this tank - any ideas on what has killed it? My gut feeling is bad luck as I can see no sign of disease on its body or on any of the other fish? Are bristle nose catfish prone to heat stress? Is 29' for a day enough to get them stress do you think?
Any suggestions will add to my growing confidence in keeping healthy fish - so far, with this exception, since reading the threads on this forum I have had a thriving cycled tank with very happy looking fish! Thanky you all and happy new year!
