Hello all,
I hope you all have a great pre-christmas-time and prepearations are going well. Only a few days ago I got perhaps one of the best gifts this year – offspring from my P. parvulus wich I had previously gotten from Bernd at the Hamburg meeting.
When I got the four adult fish from bernd in September, I set up a new 20 l tank for them as I usually do with lots of leaves, peat granules and some caves as well as a few java fern plants. The tank is kept at about 22-23 degree Celsius and a small filter is also active.
In the first weeks I mainly focused on changing the water about twice a week. I fed some black mosquito larvae but soon the weather got too cold for them to thrive so I started feeding micro worms and freshly hatched artemia. They were doing well and soon I found some eggs. However, they disappeared within only one or two days. I assume the germ concentration might have been too high.
However I kept changing the water pretty frequently and fed artemia about 4 in 6 days.
Since nothing really interesting happened At one point I felt the parvulus were still a bit above my capabilities in paro aquaristics. I only changed the water about once a week and also the frequancy of feeding was reduced due to lots of things I had to do for university and also some special events of my scout group.Now, with this going for about four weeks, suddenly I find at least 4 perhaps quite a few more juvenile P.parvulus that are already quite big and feed well on artemia.
It seems that the hifh frequency of water exchange is not the critical point or at least not the most important one. I also think that germ density might have been reduced thanks to the lesser food added and therefore less pollution. I hope I will soon be able to share some pictures with you and wish you all a joyful christmas time and a happy new year!
Greetings Rafael
Congratulations, Rafael, and congratulations to all of us. The new stock we have presently differs markedly from the first that was imported decades ago to Europe. The first breeder, Günter Kopic, complained heavily about the difficulties to be overcome. As it seems, this probably was due to individual or poplation-relative sensbilities that are obviously absent from the stock we have now. I am sure you will be still more successful with this species in the future. The main difficulty seems to be the rather small numer of eggs produced. In my experience the tiny larvae hide beneath the leaves on the ground still more effectivily than in other species.
