Black tetras on a hunger strike, apparently now it's over

[waffelo]

Strange behavior from my fishies.
I have 3 black tetras (among the rummies and rasboras), I've had them for maybe 18 months - hardy little fish. Anyway, last Saturday all the tetras stopped eating - no sign of illness or unhappiness. All three, and only the tetras.
My ph was low so I raised it, checked the nitrates - fine. So then, all on the same day (yesterday) they all started eating again, after a 4 day hunger strike.
Conspiracy in the tank - silly fish.

Heh, good to hear!

My black tetras (6 of them) look pregnant every day from eating like kings...bloodworms, mysis, brine, and they even ate some feeder guppies that I bought for my datnoid!

I was in awe.
