Fry tub airline Utube

In the floating fry tubs I like to keep things moving with an airstone. Before the eggs hatch and when the fry are on the bottom, the airstone can move around and damage or kill them. 

This is a simple little trick to keep the airstone off the bottom. 

Simply heat up a length of rigid airline with a lighter and bend it to the needed shape. 

Hugs the wall tightly and keeps the airstone off the floor of the tub.

This orignal piece was simply bent into a u. 

You can make then much more custom to the bowl by shaping to the lip of the bowl. 

To attach slide over the lip.

A little twist.

And you have a snug fit.

That will stay on the bowl.

For fine tuned air, and inline drip irregation valve can make fine adjustments or stop air right at the bowl. 

Back in place.

A tight fit.

This will also work in reverse for water using my airstone fry filter trick seen here.   Having the airstone off the bottom will prevent all the water from being removed from the bowl, as the slow flow and capillary action will drain all the water from the fry.

Pompon spawning mops

The pompons are from Oriental Trading. They are lower quality than the green poly shakers but are 1/2 the price. I have them all floating in a tub of fresh water to see how they saturate. So far it might take a while, or a wash with soap to get them fully submerged and more weight maybe needed. The smallest sinking model will work great in a spawning tub, or for a squeeze media.

The kit

Float and weights
Aluminum fishing net float and ceramic insulators for electric fences

Cut off the handle


Handle removed

Feed the zip tie through the insulator then around the pompon, back through the insulator and zip the tie

The mechanism of the tie keeps it from falling through the insulator

The cut end of the zip tie is very sharp  
Melt it with a lighter to save your buckles and the fish's scales

Mirror image conjoined twin Topview Ranchu

5 days post fertilization Suzuki x Kageyama Topview Ranchu.  Conjoined along the ventral surface (belly to belly around a common yolk).  No mouth visible.  Each eye is for one head, the other eyes are on the back side.  As far as I can tell this is the first image of conjoined twin ranchu on the net.  
Blue moon.

Asian market bowl make over

Went to the Asian market for some new bowls. The choices weren't ideal but I ended up buying this model. 

Not really blue, and with an aweful patern on the bottom.  

Time for a change. 

Bye bye blue. 

Fusion spray paint.
