Right Rüdiger! But I would bet there are a few more today… At least the parents seems to be close the spawning season for this year. All are always in the water, but the males lost their nuptial pads at the hind legs.
Normally yes, but I haven’t enough boxes to sort them exactly. There are age differences of two weeks. At the moment no problem, but I could imagine that will alter when some reached 2,5 – 3 cm. We will see
The biggest larvae are now ~ 15 mm ( 0,6 inch) and today I’ve noticed that they show a bit of “interest” for their smaller sibs. At the moment not very much, but I will sort the smaller out.
Lesser than most fish fry need. Every two or three days I clean the boxes with a sponge and fill the boxes with ~1/4 tapwater and 3/4 water from my Cobitis tanks. The hardest job is to catch the larves – 45 times the fight (have a few losses) 🙂
