Great shot John and I'm still trying to figure out how you've done it. I've got lots of little critters like this in my pond so I might have a play tomorrow - lol.

Cheers

Bit of a different subject John, but an interesting shot!

Works for me, especially as all the shrimps are in good focus. Would i be right in assuming the tank is extremely narrow?

Nicely done :toast:

Is this one of those super-narrow mini tanks John?

Whatever it is, it's very effective - interesting image to say the least :toast:

Ok - so you need the secrets !! Its an old trick really
Take two bits of glass.
Take one piece of electric cable and pull the wires out. (or get some rubber tubing )
Lay the wire in a U shape ,
Clamp the two bits of glass together with bulldog clips.
The thickness or narrowness of the tank depends on the thickness of the tube.
You then need a hypodermic syringe to get certain critters in !
Come on then lets see all the daphnia shots !!

When I was a child many years ago , I normally found caddisfly larvae under stones, and very rarely out of cover. As they spend their time on the stream bed you wouldn't normally see them floating in the water. AFAIAA cased caddisfly larvae are detritivores or herbivores.

Apparently "some jewellers place caddis fly larvae in aquariums with tiny pieces of gold and precious stones so that the insect makes its armour out of 22-carat (gold) rather than 22 twigs"

You got it David.
These above use sand grains as camo, so you wouldn't find them creeping about on Fontinalis . We always like to make things look a bit "pretty" but we have to be careful- there's a lot of clever folks out there !!

excellent shot John, and very interesting technique. Thanks for spilling the beans. I was aware of the technique, but it would never have occurred to me to make a tank so cheaply and effectively. Good to see my taxes aren't being wasted :wink:
