sick neons :(

[freshwatertrev]

hi there, over the last 3 days i have lost all 5 of my neon is it a problem with my tank or is it just a bad strain of neons????
i bought them on sunday and the first died on monday, he lost colour and went pail but seemed to be eating well enoguh, then i lost 2 yesterday the same way and 2 more today..
Tested water on monday after i lost the 1st 1 and all seemed good, i have glowlite tettra, molly and guppy's in there aswell as real plants, any help would be very welcome
Thanks

It could just be A bad strain, what are your water parameters?

 

[freshwatertrev]

ammo = 0
nitrite = 0
nitrate= 25
Kh = 10
gh = 7
water temp 25.5 c...........ATM

 

[freshwatertrev]

oh and PH = 7.6

 

[Fishkeeper26]

Your nitrate is high, what size tank nd stock?

 

[bruinsbro1997]

How did you acclimate them? Did you add them with other fish at the same time? Neons have a rep for being sensitive.

@fishkepper,Thanks for the reply
yeah thought it was high, any sugestions on how to help bring it down, i thought plants in there are there to help with that process?? All the other parameters seem good tho yeah??
Have a 180 ltr with fluval 305 filter lighting?? (will find out for u later they are new), i have 3 Glowlite tetra,3 Molly and 2 guppy, and i only know 2 of my 5 plant atm, Vallisneria spirals, amazon sword..

@Bruinsbro
i turned off the lights, I floated bag for around 20 mins, i took a cup full of water out the bag and repaced it with another from the tank and floated for another 10 min, fed fish both in tank and bag then put them in.. The same process for all my fish... Is this ok?? yeah put in 2 new guppys from same shop, seperate bags...
