Excessive bubbles in the aquarium

[Kseniya]

Hi everyone! Another new "Egg" is seeking for help Started an aquarium several months ago, the shrimpies seem to be happy thus far but recently I have noticed the emergence of numerous bubbles and a huge growth of algae (I suppose?). Can it all affect my supershrimps and are there any suggestions on how to fight the algae since the aquarium itself doesn't look healthy even though the basic parameters are fine (pH 7.5-8, Nitrite 0-0.25)?

These shrimp are known to be tolerable and easy to take care of.

Most importantly
* When the tank is thriving, don't simply change anything to Your Liking.
* You must be able to tolerate a dirty tank.
If you feel must due to the massive algae blocking your view then scrap it off or introduce snails into it.

There are algae in there, do not feed them. You can also reduce lightning.
No the bubbles won't harm the shrimps.
In nature Algae are their source of food. Don't kill off their source of food just because we human think it's not nice to look at merely to satisfy our needs and abandoned theirs.
So they are doing very well now, just do "nothing" or add snails.

How big is your aquarium and often are you feeding your shrimp?

[Kseniya]

Thank you for your immediate response guys, I appreciate it! The tank is 25lt.

Please see below what I mean;



Those spotlight looking like things on the rock are not an alien abduction ray! It's the oversized bubbles!

They were smaller in the beginning!

And are you feeding the shrimp? How often? The bubbles are from the algae, it usually means too much nutrients in the water. Nothing harmful to the shrimp but they may not breed.

I gotta say, those are some interesting looking bubbles. I’ve seen big trapped bubbles on the underside of a rock, just not above. How is it that they have not floated to the top yet...?

They haven't floated but seemed so weird. We feed them once every 2 months, just a bit of some floating food. Please note that we have 9 shrimps.
Why will they not breed?

If the algae population keeps growing, especially with lots of bubbles on the tank surface, i’d recommend cutting back or stop the feeding. From the photo it looks like your shrimp already have plenty food.

As to the reason why they don’t breed when there is excess food, i’m not sure exactly why. But that has been the observation of many on this forum (including me). These shrimp breed when their environment reaches a balance or stabilizes. You can tell if they’re full or starving by looking at their intestines. It’s a line that runs along their back. A dark line indicates a full “stomach”. But with a nearly 7 gallon cycled tank with 9 shrimp in it, you can be sure there is plenty food without the feeding.

The product of photosynthesis is oxygen. Ergo, bubbles.

Thanks again for your advice, the shrimps do look like they had a huuuuge feast so will stop feeding for now and hope that soon they'll start multiplying

That looks like some type of brown cyanobacteria. Since you say you're feeding very little organic matter must have entered your setup through some other means, maybe the substrate or the rock. Either way just stop feeding as was already suggested. Not just for now, but maybe a year or years... Once your algae/cyanobacteria population becomes smaller you'll see some berried females. Oh yeah, the "brackish water snails" here on the website will accelerate the process and then will make sure that you won't get such cyanobacteria again.
