Opae Ula, Hawaiian Red Shrimp, SuperShrimp, whatever...

Rob: Have you considered tiny sponge filters that have lift tubes?

One of those could work. Would allow you to direct any bubbles to the surface instead of having them plow through the water to the top. There'd still be a tiny bit of flow but it may be more tolerable for the shrimp.

I have, and have some sitting around, the kind with two sponges. They would probably uglify the tanks landscape. Can add media to the HOB.

Thinking over both, Jake.

I'm guessing you're talking about the weighted ones, eh, Jake? The ones I've seen are probably a bit too big for this tank. I've never seen tiny ones.

Maybe I can figure out a way to attach the uptake tube of the HOB to the tube that the 2 sponge filters share and use it instead of an airline?

I'll look into that this afternoon.

Just woke up... looked in the tank...

Strip poker Opae Ula style (with lots of losers, at least six sets of "clothing"). A mass molting.

Curious what did this. All are alive and munching as usual.

Looks like I may have to cut back on day length. Have green growing on the white all of a sudden.

They're probably just getting comfortable with their new home and nature is taking its course.

If they were breeding regularly in their old home, they're probably doing the same in the new one. Since females have to molt in order to breed, that's like what's happening (unless there was some other environmental trigger). They've got tons of new space to fill up with baby shrimp.

Thanks Jake, was quite the thing to wake up to.

Got my sponge filter and the HOB out...

[Rob in Puyallup]

The intake tube fit the sponge tube perfectly. Will hold the sponges high up in the tank, maybe above the Live Rock where I can see them. I prefer not to, but I'll adjust...

(I'll be able to see the shrimp eat, at least! (And as Martha says, "that's a good thing!")

[Rob in Puyallup]

Oh, I put a rubber plug over the tube where the airline would normally go.

You could use just the sponge filter. Since the outflow can be easily extended, you could make it work. With the air flow metered down, you can position the outlet at the water surface and have very little disturbance.

I have the same HOB on the other Bookshelf tank. Have a single sponge pre filter on it which reduces the water flow to just a bit more than a trickle.

I like the opportunity to use different sorts of filtration, never know when you'll need it.

Okay... whew... I hate putting my hands in my shrimp tanks, don't like disturbing their peaceful little worlds, but I did. Seems they're no worse for the wear.

The sponges on the filter intake.

The tank, a bit modified...
