As the Dicrossus grow up, there is a little bit more gentle aggression between them. I've still seen no actual contact but I have seen a face-off between the male with the longest tail and one of the others. I assume the one with the longest tail is becoming the dominant male and is hence now...
Exciting times :)
I have a micro-worm culture which I am feeding my Cory melini fry with. I think that would be a good food for Dicrossus fry too, brine shrimp eggs would be good as well.
I have a dominant male developing filaments on the tail, which is nice. There is also another male but the...
Sad news on the baenschi :(
But those Dicrossus look lovely, and the tank does too. Thanks for sharing.
I've found that mine aren't shy at all, so I've decided not to add any dithers, but I may put a couple of twig cats.
You may find that the pH drops a little over time, or try filtering some...
Until this weekend, my Dicrossus were in a busy tank with 35 fish including Rummies, hatchets and plecos. Tonight they're in the same tank on their own, after a major move-around involving my new 4' tank.
I would like to try and breed them.
I am considering adding some new tank-mates in...
How big is the tank, and is there a lot of decor to provide territory divisions?
A newly introduced fish will always be stressed, and if he finds that the tank is already 'owned' by the other two males, then there's nowhere he can call home.
Wow! Well good luck with breeding them and selling the youngsters for a fat profit :)
Let us know how you get on - I'm hoping that in a few months mine will be at a breeding age too!
Mine still aren't fully grown, sounds like the ones you are getting will be. They should still be fine in that size :)
I am not aware of any commercial breeding of these. They tend to come in as a 'bycatch' with wild cardinal tetras and there are plenty to go around because not many people keep...
They are usually unsexable at the size you buy them. The competitions between males are more ritual than violent. Mine often all swim around together quite happily. They are in a 120 litre Juwel Lido which has a footprint about 2' x 15" (but is tall, which makes no difference to the Dicrossus)...
My understanding is that most of the bacteria need carbonates to multiply. When cycling a tank they multiply using carbonate, so the KH drops. When the water is soft to start with, that then permits the pH to fall. I have seen this effect in several tanks I have cycled.
However, I don't think...
A month or so on from my last post, and one of my little Dicrossus is starting to show what I think might be some sexual dimorphism. Is this one a boy?
Sorry about the pic quality and the algae - I've scraped that off now!
Yes, dried-out oak (including bark) is a 'safe' wood for tanks. At least that is what I have read in several places and I use it with no problems in 2 of my tanks.
I've been reading my pleco poop since you mentioned it :) the tip about stringy poo indicating too much protein is really helpful.
When I feed red (sweet/bell) peppers to my L244s, the poop comes out red and the little Dicrossus think it's a bloodworm treat. They are so disappointed...
I find that the key components are:
-no flash
-50mm prime lens
-manual focus (instant response, not confused by reflections and the fish don't get shocked by the focusing light)
-camera that can produce quality images at high ISO/ASA (I use a D7000 at ISO 4000)
-Patience
-Gentle post-process
:)
I agree about preferring wild over commercially bred strains. I'm going to do some more research on the wild ones and try to find a nice species that suits my Rio Negro theme and is possible to purchase!
