Dead Fish This Morning!

[LastBoy5cout]

Having finally cycled my filter, all levels reading as they should and feeling quite happy about it all coming together.

I bought 10 platies on Sunday ( 5 mickey mouse variant and 5 tuxedo variant ) and a Plec to control my algae.

Woke up this to a dead Mickey mouse Platy and two of them have sizeble chunks oput of there tails. I thought it was finrot but they were fine yesterday when I checked the levels, no obvious sign of infection. Can finrot remove a chunk of tail overnight, its a very clean section, no fungus.

Also could it be fin nipping by my Tertra's ? or could it be finrot!

All advice is greatly apprecaitted.

Hey - what are you water chemistry readings ? Is the Temp and PH both OK ?
How bigs the tank ? How have you cycled it ?
Finrot normally doesnt sound like that, it goes kind of jagged and rots more than disappears.
What exactly is in the tank now ?

Temp is running around 24 Degress Ph is 7.6, the tank is 90 litres Juwel and looking at my levels ( ammonia 0, Nitrite 0 ) everything is cycled. Its been running with fish in it since early October.

I have 5 Tetra's, 10 platies, and 1 small Plec.

I did see one of the tetra's nipping the plec yesterday.

Come home form work to find another Platy with another few chunks out of its tail.

Im sure its fin nipping by the other fish.

The platy in question is looking very lifeless and lethargic.

Anyone else had expericen of this with Tetra'a and Platies?

There are hundreds of types of tetras, some of them are very peaceful, others are rather agressive and nippy, some grow tiny while while others grow quite large etc.
A commonly sold nippy tetra is the seprae tetra for example;

There are many types of tetras already listed in the fish profile index of the forum, tetras belong to the characin family of fish. Although really, you should never buy a fish if you are not sure what it is exactly.

Finrot can set into the wounded fins of fish as a secondary infection, so you should do lots of regular water changes and treat the tank with a mild anti-bacterial med like melafix or pimafix to help encourage the fishes fins to grow back healthily. You should also rehome the tetras if they turn out to be the cause of the damaged fins- do you know the genders of your platys as well?

You also bought a lot of fish in one day for a relatively small tank, you should advoid buying so many fish in one day because it can overload the filtration and cause the tank to mini-cycle, which will be no good for the health of your fish. Not just that, but the chances of introducing fish diseases/parasites increase more and more the more un-quarentined fish you put into the tank at once.

Do you know what type of pleco you have bought as well? Some commonly sold types of plecos can grow very large...

Thanks ever so much for the replies so far, have bought some melafix and dosed it up and introduced an airstone. So hopefully this will combat any infection that they may get from being nipped.

Plec wise Im afriad I dont. I use Porton Aquatics near Salisbury and it was just listed as a plec from memory.

Bit gutted about the loss of a fish, It was all going smoothly!
