So, I plan my livestock meticulously but as we all know losses are inevitable.
My Cardinal Tetras suffered last week where one ended up inside the filter, and died, (I will get an external one of these days) and for two days running I could only count 10 so I guessed that another of the shoal (of 12) must have died too.
I searched and searched, but couldn't find her anywhere. I was convinced she must have passed away and the Pigmy Corys or Assassin Snails must have devoured her corpse.
So, as you do, I bought another two Cardinal Tetras from the LFS, (whilst i was purchasing my Celestial Pearl Danios) and they've been in the quarantine tank for 5 days.
Last night I was looking at the main tank and I counted (I know, counting the fish is becoming a proper OCD now) 11 Cardinals. So I counted again, and again just to be sure.
So now it's 100% certain, I have 11 Cardinal Tetras in the main tank and 2 Cardinal Tetras in the quarantine tank.
That makes thirteen! 13! That's not right, not what I planned!?!
