The lesson for this weekend was; Floating plants ONLY in the fry tank!!
We had in there some anarchis, some java moss and a potted up blue pickerel weed.
~ Craft mesh makes awesome pots for aquatic plants. You can make them any size and shape to fit a variety of plants, needs and tanks. Just not fry tanks.
When all the new fry were in the tupperware (actually the exact container is this; http://www.glad.com/food-storage/containers/deep-dish/
I really like it, but be careful picking it up filled with water, it wants to flex) vanished, I was very puzzled as to why. I still am, but I also started examining the larger fry tank the container was floating in for things other then fry
A day later, I saw ... a leech!!!! I don't know if they prey on fry, but it was up on a leaf on the pickerel weed, and I thought "To heck with it, let's just break down the tank!"
And so that's what I did. I drained water from the tank into another "glad" through an airstone, so I could keep the same water for the fry, minus any nasties. Then, I carefully caught the CT fry with a baby food jar.
There are 4. Now in their own glad container, with a bit of very clean java moss and anarchis from a different tank. They are not
pleased. They feel better with the plants in there though. Three are the same size and the last one is about half the size, but fast as lightening. It took me 3 times as long to catch that one as all the others combined.
Once I was really sure I had all the baby bettas out, I took out every plant and leaf, shaking them carefully and putting them into a separate container of water, just in case I missed someone.
I did the blue pickerel last. I shook out the roots and Holy aquatic life!! There were bloodworms and caddis fly larvae and the leech's little brother, and some evil looking, bright red, segmented, wormy-looking insect, about a half inch long.
~Some species of caddis fly have carnivorous larvae
~Ramshorn snails will eat the protective silk cocoon some species of caddis fly larvae spin
~A truly startling amount of life can hide in the 4x4 inch roots of a blue pickerel weed
I left the tank set up for 24 hours and checked it several times in case I missed someone, but no, we're down to 4 baby bettas from that spawn. And there is something in that tank that is a nocturnal predator. It was empty save for water, bugs and some detritus. There was a good amount of mosquito larvae in there along with everything I shook out of the pickerel weed roots - but not this morning! There's less then half the amount that was there last night.
In a few minutes, the water and bugs will be poured out into the back yard, the tank thoroughly rinsed out with the hose, and set up again.Once I've got some pairs conditioned, we'll try again.
The CT 4 will remain in their glad until I can get a net breeder box, and they can grow in that in the community tank - we're going to see if the presence of other fish and the strong filter negates the growth hormone effect.
I think the floating plants can be saved, but the blue pickerel weed was executed for it's crimes of harboring the enemy and accomplice to fry murder.
