Weird deaths
 

There are 2 type of loaches cohabiting in my 422 for a long time. CL and zebra loach. Today I came home to find ALL 3 of my zebra loaches dead. The rest of the teammates which include 9 CLs appear to be fine.

I have recently added a few small CLs, so not sure if that had triggered a gang war amongst the loaches.

Else, any other possible explanations?

Today saw some signs of bacterial infection on my big tfbs in the same tank. But the gf and cl appears totally ok.

But anywayz, doing a massive water change now.

After the wc, the infection signs appear to be almost gone. Besides changing water, i also changed the filter wool in the ohf. I have not changed it for 1 month plus, reason because it wasn't clogging but guessed i was being toopid, should have replaced it even if it wasn't clogged.

Sorry for your losses.

But don't be too hard on yourself, I would not change my filter wool if it not clog either.

Sudden death syndrome ... It happens:o

Yeah lor. Only strange thing is only all of the same species are affected.
