The Oto Journal

Got home today and didn't find any eggs. Hmmm...disturbing. I only had a couple minutes to look but didn't look good. Now to try and figure that one out. On plus side...I found a fry that I would guestimate about 4-5 days old! They must have a secret hiding spot for eggs now. I'll do some more looking either tonight or tomorrow and then tank maintenance.

Pleasant surprise today. While I didn't find any eggs, I did find one freshy hatched fry. While searching for others, I started seeing more older fry. I wound up counting (6) now that look to be approaching a week in age. Very nice! I will still have to do a small water change today and will do so slowly just as if the eggs were hatching tomorrow as was expected.
 
Update 17-Oct-2011

Big update from yesterday. Only big by virtue of action taken in the main breeder. The Hydra are really popping up and I needed to take immediate action in this tank. It was finally time to dose the tank with Flubendazole. As nerve wrecking as it was, it has to be done.

Hundreds of shrimp zoea floating in the tank so I'm sure the Hydra are staying well fed. Time for them to be erradicated.

I moved the Briggs out to another tank. Then, I mixed just under 1/8tsp of the Flub with tank water and poured it behind the filter media. I did it that way so the media could catch the undisolved particles.

Now we wait.

Good luck treating for Hydra with Flubendazole. I'll keep my fingers crossed as well.

Have the hydra been posing a major treat to the fry in the tank? Have you seen them feasting on any wigglers?
 
Haven't seen any feasting going on but the potential is there for the wee ones. That and with the zoea that wind up in the tank, makes it for a right setting for them. They have to eliminated as the ladies can't work on the leaves with them there.

No sign of Hydra yesterday. I only focused on the areas where they were prominent. I'll get a much better scan of the tank today. All shrimps and Otos (even the wee ones) seemed just fine.
 
Update 25-Oct-2011

No signs of Hydra for the past few days. Have scoured the tank as best as I could for signs. Started to transition the tank back to normal. Began with a 50% water change and put carbon in the filter. Will run it this way for a week and repeat the process. Probably won't be for another couple weeks (at least) that I try to re-introduce Briggs back into the tank. Ninja shrimp continue to do their thing. I'm still finding zoea all in the tank. Flubendazole appears to have done it's job. Now we wait to see if there is/was any impact on breeding. {crosses fingers again}
 
Been a few days since the big water change. Things still looking good. No further loss of shrimpies. Will be removing my last two juvies out this weekend.
 
Update 13-Nov-2011

After weeks of nail biting after the Flubendazole treatment, I can finally relax. There is a spawn in progress. Whew! I was so worried even though everyone was trying to reassure me. I didn't bother trying to count the eggs at the moment since more eggs are being laid every time I go down there. I am trying to minimize my travels for now. I'll get some pics and a count later. Right now, the majority are being laid in the Ludwigia area.

Yay!
