I’m trying to maintain a culture of Daphnia. I had a go with a small 12 L tank with an air pump, this was set up in my garage, the temp did get low (<10 C) but didn’t freeze. The daphnia survived a few weeks but gradually declined in numbers.
I’m now trying indoors with a 5 L jar, it’s got some dead leaves + some floating plants. My plan is to syphon our a pint a week (with daphnia), pour the daphnia in my tank and top up with tank water.
Previously I tried feeding the daphnia with Alison’s baking yeast with vitamin C. I did this every other day. I noticed that a layer of dead/dormant yeast formed on the bottom of the tank.
I’m guessing I overfed the daphnia, the cold water caused the yeast to quickly drop out and putrefy on the bottom. This probably led to ammonia and daphnia dying.
This time I will proof the yeast at room temp using tank water and I will feed less, probably once a week.
Does this sound like a sensible plan?
Is the vitamin C toxic to the daphnia?
Any daphnia tips?
Would like to make this work as I want to try and keep fish like scarlet Badis + all the fish enjoy chasing daphnia! Thanks T
