My new Hinomaru's

Hi everyone,

Before I ask my question I just wanted to let you all know I finally have snowflakes that are about three weeks old. I also have babie Greens which are only a few days old, (dang they are tiny.) All my other shrimp are doing well. My Crystals and bees have babies also and believe it or not they are not hard to find in the 55 gal. tank.

Ok now to my question, I have had a ten gallon tank set up for several months, its actually the tank the greens and snowballs were not breeding in so I removed them and left the tank up trying to decide what I should do with it, well I found something (Hino's). My water parameters are good,

Ammonia .0
Nitrite .0
Hardness-moderate hard
P.h 6.6
temp 24c, trying to lower a degree

Ok, I have a sponge fiter in there and if I turn the air on to it my shrimp go to the top of the tank and partially out of the water and they do this only where the air bubbles are at nowhere else. If I turn off the air to the filter the shrimp all go back to grazing, whats up with that? Any Idea what might be going on?
Should I take out the sponge filter and replace with an overhead filter thats in my 55 gallon tank? My 55 has a Ehiem 2128 on it plus two small over heads, so I think I could take one from there.

I plan on putting the Hinomaru's in a 30 gal. in a few months, so the ten gallon wont be their permenant home.

Congratulations on the success with all of your shrimp

! If you get a chance please post some pictures

You can try this. I think your shrimp are being stressed out by the bubbles since this is the only time you are getting the reaction. You can also try raiseing the outlet/bubble end of the sponge filter above the water to avoid producing bubbles

Thanks neon for the info. I was not able to raise the filter so as to have the air bubbles higher, but I did slow the bubbles down and that has worked real well as they no longer go to the top. And they have certain colored up real nice since their arrival.

My babie Greens are swimming around the tank today for the first time, still amazing how small they are, but I think they are doing very well.

Good to hear that things are working out for your CRS and green shrimp

.

I think all of my green shrimp (6 of them) are females. They are all the same size and 4 of them have saddles, just no male to mate with

Maybe one day

Heather, a thought, when a seasoned sponge filter is used with a high bubble count sometimes very small food particles and minute water fauna/flora are sucked out of the sponge and scattered into the water column. I witnessed this in some of my tanks, my solutions were, rinse the sponge more often & the best solution was to reduce the amount of air to the filter, thereby reducing the pull on the sponge.
