Sick Fantails + Goldfish

[Pebblo]

Hello all, I'm hoping some of you may be able to help.

I have 2 60 liter tanks (one I'm using for tropical, one for coldwater).

I've been cycling my tropical one for a while now and its been fully cycled for 2 weeks (still running it on household ammonia atm as I intend on planting it up)... anyway, after the test week in which I knew the tank was fully cycled I took out the white media and placed it in a coldwater tank replacing it with new media (They both have PF2's in) I used a heater to keep the temp up an gradually lower it over a few of days and it now has no heater.

All tests from my master kit were fine, 0 ammonia, 0 nitrite and 50ish nitrate i think. My intention was to leave it running for another week with 2 goldfish and see how it was then, but I was then given 4 fantails fish the next day. So they had to go in the tank. I monitored the test again after 12 and 24 hours, and the ammonia was still zero, so was nitrite.

I was away for 3 days then, asked the g/f to keep an eye over them.

Well come home yesturday 2 the news of 2 dead fish (1 fantail and a goldfish) and that the fish have whitespot. I've added Interpet Anti Whitespot as I already had some and done about 70% w/c (I tested that before drainign and ammonioa was about 0.5, Nitrate 0.

Since then 1 more fantail has died (didn't look to good when I got home) I know fantails and commons shouldn't be kept together, but the commons will be moved to a large pond by the end of this week and surely that can't be causing them to die?

Any advice is appreciated.

its good you added old media to start the new bacteria colony but you have to keep feeding it ammonia to keep it going...so ultimately you may have started a new cycle...too many fish as well leads to stress and disease... new tank syndrome as well with everything starting over.

once fish get stressed and immunity lowers they are susceptible to a lot of diseases. mixing wont have done whats happened no... and in a 60 litre tank only the one fantail and maybe a couple loaches.

as for the fish now..raise temp to around 30c and keep overhead lighting off when treating. some fish will make it others wont.

keep an eye on the tank to see if it is cycling

Cheers for the reply.

I couldn't add ammonia to the coldwater tank to feed the bac's while I had the goldfish in, or could I?

If I keep an eye on the ammonia or do a water change twice a week, would I be able to keep the 2 fantails in this tank? Theres 2 silver fantails the g/f would like to keep (its more for the her as the tropical tank is mine)

One of them has a kind of brown mark on its head and by the beginnig of its back fins. Is this caused from stress or is this something else I need to look into?

no theres no need to add ammonia if fish already present.

you can get away with two fantails just make sure water changes are kept up and plenty of filtration. the browning on the head and fins could be a colour change as some goldies naturally go through a few colour changes in their lives. if its black then its more than likely ammonia burns which are healing up.
