The Oto Journal

Update: 12-Dec-2010

Fry Catching Day! Oh what fun. Taking a quick break. 15 minutes in and only caught 8 so far. Gotta luv it! I can't use my trap with how many shrimp are in there....but then again...maybe get it set anyway and use it as a secondary method. Hmmmmm...why did I just think of that. I can always fish out the shrimp later. ;o)

Back at it.
 
Fry catching for the day is done. 20 little fry guys are acclimating to the holding tank. What a challenge! lol. I'll slowly work on the rest throughout the week. My trap worked a little bit. Wound up even catching one of the Briggs. He got out before I could get the camera.
 
Update 15-Dec-2010

While checking on the Propinqua shrimp this morning, I noticed eggs next door in the holding tank. Good sign as the latest additions to the tank didn't have any impact on spawning. Now the question will be of course, are these going to be good eggs or not?

It's funny, how these spawns always seem to occur the day before a scheduled water change. Interesting. They aren't set days either (just to rule out a timing thing). I just tell myself "self...tomorrow you will do a water change". :)

And another interesting find in this tank, I saw a fry that is only a couple days old this morning as well. So obviously, there was an additional spawn (partial probably) that went undetected. I never saw any eggs so must have been in the Java Fern.
 
A late check of the tank last night, and I discovered one non viable egg at the time. A couple looked to be on the fence this morning so should know about those come this afternoon. Did a 10% wc yesterday to follow up with an additonal 10% today. Zucchini is going bad much faster than usual which isn't good but the parms are staying right on par. Heat looks to be hovering around 74 at the moment.
 
Update 17-Dec-2010

Was able to physically count (19) wigglers today. Found about (10) non-viable eggs from this batch. This one is a bit odd too. The fry are actually bigger than usual. Real pudgeballs this go round.

Doing another 10% water change and prepping fresh zucchini.
 
Catching little guys from the holding tank was a fun little task this morning. The fry kept getting in the way. From the newbies to the ones that are a few weeks old. I would place the net over a juvie on the glass and one of the fry would lite just above it preventing me from sliding the net upwards. Sometimes they would even lite right next to one I was getting ready to net. Was comical actually. ;o)

Stirred up a couple of huge females during this process. There may be another spawn in the works within the next couple of days. Activity levels are on the increase again.

Will be pulling the remaining juvies out of the main tank between today and Sunday. I may decide to do some trimming in there at the same time.

Getting close to the 100 mark of Oto's rehomed. May have to do something special for that milestone. Maybe offer that package free of charge (not counting shipping of course) to the lucky person. Have to do something kewl.
 
Have you heard back from the new owners of your fry and found out what the survival rate of the otos have been in their tanks?

I'm just wondering how tank bred otos compare to wild caught ones in the 'hardiness' scale. I would guess that there is a much higher chance of survival, but how much higher has it been?

I recall hearing of a couple of casualties. One was due to owner accident if memory serves me right. I will, from time to time, hear back from people letting me know how they are doing. As a matter of fact, just yesterday I was contacted from a person who purchased a group a few months back. They wanted to let me know that they are still doing well and are fat and happy.

Now I haven't heard from everyone after "x" period of time, so I can't say for certain how others are doing. I do know they are shipping at 100% between express and priority.
