Cause of death?

Recommended Posts

Hey everyone,

wondering if u can help me out here...

Noticed one of my furcatus (sp?) rainbows not looking too good yesterday. Seemed to be swimming slowly round the top of the tank and its mouth appeared to belocked open. at some times he was right up at the waters surface and just hovering around slowly.

Sure enough he was dead this morning, mouth still open.

otherwise he looked fine.

Any idea what happened here?

All other fish seem ok, PH, nitrate, nitrite and amonia tests all A OK.

Cheers, any ideas would be appreciated

Hey dude.

If it was puffing with it's gill covers prior to death, then most certainly died of respiratory problems. u've basically got the problem localised to the gills( possible but less likely to b blood or heart problems)

if u then rule out water quality problems( don't forget temperature, toxins/posions--fly sprays, medications, sturring up the gravel can release toxic H2S n methane, CHLORINE/CHLORAMINES), then think infectious diseases.....gill flukes, large list of protozoal oragnisms....bacterial..fungal. etc but even with infectious bugs, usually need something in the enviro to predispose n precipitate disease.

also, the fact that the other fish r all sweet does go against a water quality.

what to do from here?

watch the others closely.

water changes, u can't go wrong. it'll improve any potential water quality prob, dilute any bugs shed from the dead fish etc etc

add some salt ( 1 tabletspoon per 10L) this is a small dose safe for most freshwater spp

hope this helps
