Mike I'm afraid your thread was inadvertently deleted - really sorry. Would you mind posting up the pics again?

no problem,

Ok... after maybe 300 bad shots....something:

this is a total accident, the babies mostly run in the substrate, and run quickly enough that I cannot focus. For size comparison, confusona is about 3.5".

I found one way to photo them... bury food (brown disc -- Hikari carnivore wafer) at the front glass.... this makes them dig their way to food and photo'ing becomes easy :D

Thanks Mike. How are they getting on now?

Thanks, Matt,

They seem fine, and I probably should not worry about them at this size and speed. Very likely it is 10+ but I probably will not ever know the actual count... I'm only concerned that the tank may end up overcrowded.

They are getting more confident in the last few days... not reluctant to fight the parents and confuzonas for food and have a pretty powerful bite for 1" fish, I can see them biting the wafers.

Not having to do anything, only watch, is most enjoyable. :D

Possibly I was thinking too high about sinibotia dangers... not only they seem to be paying no attention to the babies, but the kuhlis managed to displace one of the sinibotias: it dug itself a cave under a filter, but now hides in a corner and the cave is filled with baby oblongas.... this is a fat seemingly healthy 4" sinibotia, chased away by 1" fish. :D
(Another sinibotia shares its space under driftwood with both parent and baby kuhlis, the 3rd owns a spot that kuhlis would not like.)

Not sure I'd like to sleep on a bed of pangios either. :D

Yep... :(

Jokes aside, I'm a bit worried about the well-being of other fish now. There seems to be a dozen of them now... not in increase in fry count, but they are getting more outgoing every day so I see more of them ... and they are quite obnoxious, and what they cannot do by size they achieve by numbers.... It would be sad if they outcompete confuzonas to death... (I thought that H.confuzona is about the fastest fish in detecting food.... no more, the babies get to food first and push confuzonas away).

As a variant: to put food in different parts of the tank at the same time.

Sure doing this... but it is not just the feeding time, 29g is too small to provide hiding places for all of them, and oblongas are clearly taking over. Well...we'll see.

18+ I'm now pretty sure of.

=====

Seriously offtopic question: I'm tempted to move a bit more in this direction now.... will likely add a couple more of kuhli tanks... but perhaps try a Mastacembelus group too? Did anyone succeed in spawning them, and/or recommendations on the best species to try?

That's a very decent number and makes me wonder why spawning pangios is such a rare occurrence. How old is your adult group Mike?

I owned them for 8 years... no way to know the age, but I got full-grown fish originally.

The reason is most likely improperly set up tanks and possibly food. Mike Hellweg in the US bred 3 species -- so this is not a rare occurrence if one does things right...

BTW, here is admission: Ironically, in June, at about the time my oblongas spawned I felt so frustrated about years of no kuhli breeding that I bought two groups of kuhli fry... while neither is ready to breed yet, this at least assures that I have enough of the same species -- with kuhlis one issue may be that different species (or even locales) do not hybridize, and it is hard to know if one has one species or not.
Interestingly, the p.semicincta babies turned out to be very fast growing.... nearly adult size already... but the other group (either p.malayana or p.cuneovirgata) the growth is not noticeable...still thin and tiny (1").

8 years, impressive! Are details of Mike Hellweg's experiences available anywhere?

Regarding different populations we caught very similar-looking looking kuhlis throughout Malaysia so that definitely makes sense.

I think they live up 20 years or more... I did lose 2 out of 7 over 8 years, but the losses were my mistake (don't keep kuhlis with BN's!).:

As for Hellweg: no, but I know that he bred P.myersi, P.semicincta, and -- this is not certain -- P.doriae. He definitely used a lot of live food (he is the author of a book on live food).

Regarding different populations we caught very similar-looking looking kuhlis throughout Malaysia so that definitely makes sense.

Did you take any photos? That article I believe I saw (but could not find again) had a map of locations/patterns, but what are locales and what are possibly incompatible species is of course unknown...

Yes plenty of pics of both fish and habitats. As soon as I'm properly settled into my uni course I'll start posting some up.

Not a hq video but just to give an idea of how the feeding looks like.

feature=youtu.be

Confuzona's are the only ones who try to compete, other fish is afraid to approach the swarm.

Good grief, Pangio plague! Those are some chunky-looking Homaloptera as well. :D
