Bubbles in larvae

[misslyss]

Literally just did a water change on my Noto larvae that are kept in separated containers and the largest of the larvae has developed air bubbles and keeps floating to the top. He swims down but slowly floats back up. Is there anything I can do? Is it possible this will go away on its own?

I think I've heard lowering the water level so the larvae is closer to the bottom of the tank helps, but I'm not positive.

yeah this happened to one of my cynops larvae after a water change too. It went away without any special treatment, dont worry. keep em cool as possible.

Just this happen occasionally. Just wait and usually it will fix itself. The idea to lower the water level is so that the larvae feet touches the bottom making it less stress, and lowering the water level also give it better chance to hunt for food as live food frequently stay at the bottom.

This problem is likely to be caused by the water change, actually. If you are doing 100% water changes, be sure to do them every day, or every 2 days at the very least. The alternative is to keep the larvae in a larger container with lots of live plants (ideally, a pre-cycled tank) and just do partial water changes/cleanings.

Thankfully, the bubbles disappeared and the larva is back to normal. Thank you to everyone who replied!

Jennewt, I know the air bubbles were caused during the water change. What I meant was it had literally just happened right before I posted the thread. I keep them in separate containers so the larger larvae don't prey on the smaller ones, and also to make sure each one is getting a sufficient amount of food. I do water changes every other day and I use aged water bought at the local pet store. This technique has worked great for me for about 1 month.

Wow.. you have to buy aged water from pet store?? That must be a lot of money and hassle. I simply use tab water aged for one day in a bucket so that it reach room temperature. I do add water conditioner when I fill the bucket up. It worked for many species that I bred.

In addition to what Jen stated I find lowering the water temperature and frequent smaller feedings also help prevent what I call zepplin larvae.

lowering the water temperature and frequent smaller feedings

Will lowering the temp cause the larvae to grow slower?
