A very strange thing happened! (At least it was shocking for me)
I set up a new breeding tank couple of weeks ago, just because I could realise my platies were getting extremely fat, carrying little eyeballs of fries in their bellies. I thought I may need to seperate the babies. But they are, now in breeding traps I have over 40 platy fries (cannot let them swim in the new tank). Meanwhile I thought I may give a try to my Blackskirt Tetras (blackwidow) to let them have some fun in my new 35 lt Tank, indeed they don't spawn when they are in the community tank. 2 days later I got bored I took them and put them back to the community tank. But before these happened in my new little tank I put a drift wood which is a big size wood ( first I boiled it 1-2 hour ofcourse, and kept in a bucket of water for a while). This wood made my water extremely brown , some kind of jelly look like cover on the wood made different things alive, so I had micro worms in the tank, water looked really disgusting. I made the test it was kind of acidic and NO2 was high so I changed half of the water and changed (the water is still brownish) the decorations many times, just because I didnt like the setting. But I put many different types of plants, no rocks, on the bottom plastic coated pebbles. On the top of this aquarium I have been using the light for my brine shrimp hatching set up so the light has been usually on. I need the little brine shripms to feed the fries. Then all of a sudden 10 days later since my tetras left the little tank, today I have found some little creatures, ugly fries in the tank!!! I couldn't believe what I see!!! How could they survive or how is it possible that in that water my tetras had fun!
Now I could see 4 fries, I am not sure if I will see more. I don't know what they eat there since I have not put any food there, how could they become more than half a cm. They are fairly seem like Blackwidows. Now they are in the little breeding thrap with my recently hatched platies (new additions). I just thought when I found them, I guess it happens in this way in the nature, they just survive. And Accidentaly I believe I have made a blackwater which they like and fries had survivals. Even I scrambled everything the tank 100 times they survived and could find something to eat! Unbelievable!
