The other day when I got up I noticed that I couldn’t see the fish any more. Totally disappeared. I guess my crayfish had a good snack that night. 🙁
As I was scooping it out of the tank Elliot was asking me about what I was doing and why. I told him about how sometimes when pets get old they die. I stayed away from mentioning Yoshi.
Of course Elliot being a boy wanted to see it up close and personal.
I will have to keep on top of the population. My co-worker who gave me the 4 crayfish still has too many of them and I don’t want a repeat of my snail problem.
I chose an Otocinclus. This fish attaches itself to the side of the tank and eats the algae. Occasionally it swims around to another location, but most of its time is attached to the tank.
I also cleaned the tank this week. After moving one of the decorations, I caught a glimpse of a teeny, tiny crayfish. It is still alive. Cool. Hopefully it makes it. Right now the crayfish is about a centimetre long and dark like the rocks in the tank. When it doesn’t move, you can’t tell it is a living creature.
Right after I turned the light, out the corner of my eye, I saw a flash of movement. A tiny speck was hanging on to the back wall of the tank.
Looking closer I saw it move. It was a very, very tiny crayfish. At least one of the babies has hatched.
I fed the fish then watched as this tiny crayfish tried to blend in with the rocks and other decorations. I guess it was less than 5mm long. Very, very hard to see. I’m curious what happened to the rest of the eggs in the sac. After seeing one crayfish with some eggs, I later saw a second carrying eggs and making a bit of a nest under the rocks.
Curiosity is strong though. I want to move the tank decor to see what is going on underneath, but I also don’t want to disturb them tiny creatures. When they are ready they will make their way out. I’ll have to be careful next time I clean the tank though.
One of my crayfish is cradling a clutch of eggs. From what I just read they should take about a month to hatch. The guy I got the crayfish from started off with only a couple, and eventually had 20 or so.
We’ll see what happens.
I looked a little closer, and the only crayfish that I couldn’t immediately see was the smallest one. Looking at the shell pieces I decided they were too big for the tiny crayfish. I moved a couple of the decorations and the tiny crayfish bolted.
One of the crayfish must have molted. Today I asked my co-worker who I got them from and he confirmed that they do that about once a year. Cool.
Tonight I dropped the bag in the tank, let them acclimate to the new temp, then released them.
In all there are four of them, a really big one that likes the rock cave, then three other smaller ones that are still sorting out where they want to be. Very cool addition to the tank.
If anyone is looking for some crayfish of their own, my co-worker has lots to go to good homes. Use the contact link above if you are interested, and I can pass your information along.
