Here's my mystery for today!
On 10.25, I put the following into my 25g tank:
Malaysian Trumpet snails x7
and two plants that had been sitting in a unheated, unfiltered bucket of water for at least two weeks:
I did not
add any of the water that the plants or snails had come in/been sitting in. I did not scape it, the plants are just sitting in the tank and chilling until I get around to it. I added the plants at about 65 degrees, then warmed it to about 77 degrees, where its been since. On 10.27, I added filtration and seeded with old gravel in a knee high. I added a small amount of granule fish food. Amazingly, the tank has appeared completely cycled on and since that day. Pennywort, Hornwort, and spiralis have shown nice growth. Snails seem happy.
So the mystery...
Today I was doing my usual snail check. (I only want the MTS, so I've been on the lookout for any invert hitchhikers.) To my utter surprise, I saw not snails but- FRY!
I saw at least one fry that was about 3/16" to 1/4" long, clear, elongated body, hanging out in the Hornwort. I also saw about a dozen very small white creatures that were about the size of a period, but with a tail. These quick little buggers seemed to be grazing the back wall.
Unless these critter hatched from eggs that were on the plants, I'm not quite sure how this happened! I'm not ready for babies!
I understand that IDing these creatures is about impossible at this point, but if you have guesses I'd love to hear it! So to my question... I think the larger fry could eat powdered flake. I've cared for fry this size, I think I can manage them. But the itty bitty things... I'm really doubtful they are fish. BUT, if they even ARE fish, I've never had to feed something so small. I really don't think they are fish, but I'd hate to NOT feed them and then find out I'm wrong and I killed them. I don't know that I'd start culturing daphnia or hatching brine shrimp or anything at this point in my life. So I'm wondering if I could use a dry oak leaf for infusoria. What do you think? Do you think that would be enough to get them big enough for powdered flake? That is, if the tiny creature are, indeed, fish and not some bug or whatnot, of which I'm doubtful.
Thanks for your imput!
