Neons Acting Teretorially.... Help

[david321]

iv just set up a new tank for my brother. iv had neon tetras in my tank for bout 7 years, nice n easy. however i put 6 in my bros tank a few days ago, however one of them just chases th rest aroud all the time, and it looks like 2 have died. theres no reason why they would have died due to poor water or anything like tht, so i wondered if any1 new y one was chasin the rest round and also is it likely this 1 has just chased the others to death n worn em out?

feedback would be a big help, cheers!

What size is the tank? What other fish are in there & do you know the water parameters?

its 3 foot wide by 2 foot tall by 2 foot deep. approx 90 liters. no other fish in there yet, just the 6 neons. and will add more as time goes on, but neons seemed a logical place to start.

3' x 2' x 2' is about 340 litres and 90 US gallons. Neons should have plenty of space in that

You could try moving some decor around to try and break up their territories?

is the tank cycled?

 

[lilfishie]

they'll probably just be sorting out who is boss, and with only 6 in a tank that big will feel unsecure

I agree with afishdude, is the tank fully cycled? how long has it been set-up for? I know that neon tetras are very sensitive when it comes to acclimatization and they should be acclimatized using a drip method. How long did you acclimatize them for? What are the water perameters? What type of filtration are you running? Are you sure the
heater(s) is/are working correctly?
