Hello, this is my first time posting, so correct me if I do something wrong.
I recently got a fluval Ebi from a friend (I have never had a nanotank before and I thought I'd try shrimp or a betta). and I set it up 12 days ago. I have a organic soil base with shrimp stratum on top. When I filled the tank I used mature water from my 40 gal and aged tap with water conditioner, and used some media from my other filter as well so speed cycling along. For plants I have plants from my other tank (hornwort), some throw aways from my friend (the jungle val and bacopa), and duckweed and some mystery plants I got out of a pond. The plants are doing well aclimating and I was reasonably certain my only inhabitant was the one pond snail I got from the wild plants, but then I started to notice hydras.
Before going out and getting fenbendazole (which I have used in my other tanks for hydras), I decided to try to kill most of them with warm salt water.
This killed a decent amount of hydras but as I was flushing the salt water out I noticed a baby fish in my tank. I have not introduced any fish so i figured eggs must have been on the wild plant or a mosquito fish fry could have eluded me for a while, though it's doubtful. I put the end of a pair of tights over the filter intake and got the water taken care of. About two hours later there are 3 total fish fry, and this morning I'm looking at 5 fish in my tank. I am highly doubtful 5 mosquito fish fry could have avoided me for so long, so I'm pretty sure it's an egg laying fish and they came in on the plants. Any ideas what they could be? I got the pond plants from Aiken, South Carolina.
Regardless of what they are, I'm excited because wow I have set up this tank without spending a single cent!! including fish apparently!!
(sorry about the cell pictures)
the first fry isolated in a jar as i replaced the water:
