I thank you all for responding and I appreciate the ideas. I had a thought that a LFS might take them, what's that usually like? Any of you have experience with that? Do they trade or buy or both? I'm not part of any major social media (FB, Twitter, Instagram, all no) but CL is an option, especially if they keep coming as I suspect they will.
@gardenman not only was I NOT trying, I didn't WANT them to! Ha! They are stupid cute though. When I saw the first transluscent Oto stuck to the glass I thought I was seeing a bug in my tank but when I realized what it was I could *not* believe it - I'll admit to giggling like a madperson and maybe squeezed out a happy tear they were so stinkin cute. @Hobbit and @Maggie it's good to have concensus that LFS is a good place to start. I live in a pretty large city and have a few LFS I can try, I'm hoping the place I got them from would be interested, because the first set I got from a different LFS all died within days but for one, the six I got from the 2nd LFS all survived.
@CT_ Like I mentioned I wasn't trying to get my Otos to reproduce so I didn't feed them anything special so as not to encourage them- my tank has plenty of algae and I literally have a small fish-shaped "fish bowl" in the tank that I put a piece of Hikari Algae Wafer and a couple of small pieces of Xtreme Cat Scraper in every other day or so and I can say that I've spotted some of the smalllest fry in the bowl. 6 of the adult Otos I have when in quarantine ate Hikari Wafers (due to lack of algae in my quarantine tank) so I continued to put it in my established tank in case they got picky, but were never interested in the Xtreme Cat Scrapers- my Snails love them though- seek them out all the time. I chose to do a low tech tank, so I don't run a heater (today's temp was 76.3), run full spec lights on a timer and a dimmer switch, PH is a steady 7.6, Allkalinity at 3 or 53.7 GH at 125.3, all the other readings typically at 0, have a sponge filter rated for a 20 gallon (that the adult Otos ALL hang out at during the day), some driftwood (which I suspect one of my females is laying near), some live plants and some imaginary (what I call fake ones) in for color, the substrate is fairly large pebble river rock with a bit of plant substrate under towards the back of the tank. I do partial water changes every week. My Mystery snails also keep trying to reproduce. My Harlequin Rasboras have made no moves to reproduce but are happy and brightly colored, however now that I've said that I might have to eat my words.....
