Stephen's 550L tank log:

[Stephen]

I have adjusted my signature as I only counted 16 x serpae tetra (and 27 x black neon tetra).
I'm not 100% certain on the numbers but watching them shoal is easier to count, they may be the odd one that did not shoal.
I just observed my male apistogramma trifasciata struggling near the surface of the water, I'll keep an eye on him.

I have had him for a year.
He was a "wild caught" apistogramma trifasciata and had grown to almost full-size, the colouration had developed nicely and he appeared fine yesterday.
The above photo was taken last August and does not do him justice as his colours were wonderful.
The female is still there.

Stay safe & healthy everyone

That's a real shame, any idea why @Stephen

Thanks Martin

I did remove some plants the other day but also syphoned the substrate to remove the plant substrate that was disturbed and also done a large water change.
I also done some filter maintenance the following day on filter 1 but left filter 2 alone.
I lost a serpae tetra yesterday, probably not a coincidence now, but parameters are fine.
I use Seachem Prime as my dechlorinator which also neutralised ammonia & nitrite, unless there was an undetected mini spike.
I also tested the water temperature which was spot on.

Sorry you lost him.

I am in contact with Steve @ Aqualife for a replacement male, he's checking stock for me as I'm making a small order up to make the delivery worth while.
