Okay this will be a little tricky to explain but since 26.04.2008 I just cannot take it out of my head.
This beautiful Saturday I've met Evert van Ammelrooy and his friends (he gave a lecture for our Tanganyka Geeks Club in Krakow).
It was really great. Lot's of great photos of Cichlids (some really, really rare) and a part of lecture (about 30 minutes) was about catfishes and other non-cichlids - mostly Mastacembelidae and shrimps. There was a photo of 10 cm long Clarias species. Yeah, I know there is no so small Clarias and for sure not in The Lake. Those in lake grow huge and live deep. This one was so small and was found only on 10m deep.
In the evening I've met with Evert and his friends on not official after party ;) and I got a possibility to talk about this dwarf Clarias.
He ensured me few times this fish were mature and full-grown. He saw a group about 20 of the same size feeding on dead fish. Location: Funda, Zambia.
There aren't a lot of papers about Clariidae and if there are I cannot get them. Again there is almost no data about Lake Tanganyika Clarias species beside they grow big and live deep. I am very exited about this

I know that seeing a group of this fish is not so strong argument. We all know behaviours of fish my change with age. On the other hand after few years in a hobby you know if fish is mature or not even if it is not full-grown because of some sickness or wrong habitat in early stages of life. And you have to remember that Tanganyika is very special lake with a lot of dwarven forms of fish

I got this photo but I cannot share it with you guys :/, I will try to change Evert's mind

Regards.
