Orange & white looks like a Yellow Melonachromis Johanni (I think female).
Very emaciated looking - I personally wouldn't touch that fish if I saw it for sale.

It could have been getting bullied in its previous home hence not getting its share of food so it could be fine.
On the other hand it could be an internal parasite which is not so fine..

Difficult to ID the others though I have to disagree on the Id of the grey blue fish as an electra. Not sure what he is to be honest but he doesnt have the black line through the eye that you see with electra.

I think the grey/blue fish looks like a cynotilapia afra varient, also i dont think thats a peacock looks like a pseudotropheus tropheops, which can be aggressive!!!!

Hi all,

Hope you can correctly interpret the following readings for me?

Ammonia 0
Nitrate 10
Nitrite 1.0 (This is the one I'm concerned about!!)
PH 7.8

I was going to feed them this evening but not sure whether I should do a partial water change first given these readings.

Would appreciate some speedy replies.

Ben

Yes a 20% water change would be in order. Test the water & feed tomorrow, missing a feed today is no harm

Hi Ben, i wouldnt feed them, leave it for a few days do a waterchange asap however this will only dilute your NO2 it will rise again, if you can get some safestart by tetra this will help, it really works!!!! keep testing the water daily, dont touch the filters for now.

Zale, thanks for the reply. Do I need to do the water change urgently this evening or will tomorrow morning be OK??

No do it straight away.....

Ben even a 30% would be ok, I would even feed them maybe twice a week until the parameters leveled out and leave the lights off so they don't feel as stressed.

Are you using a declorinater in the tap water. Sorry for asking, just making sure.

Do Just as serratas has said.

Hi Zale/Serratus,

Thanks for the reply.

Am so knackered after a really long day but gotta do the right thing so will drag myself up and start emptying 100L out of the tank!!

Yes, I am using a declorinator but will also get some safe start in Baumans tomorrow morning.

Ha...use to kill myself with bucket after bucket of water, now I use 5 meters of garden hose and siphon the water straight out the back door, much quicker.

Good luck with the 100 liters
