Fun with the lights on? I'd say! We have a very interesting dynamic appearing in our tank. A few weeks ago i had really good gravel vac under all the stones and bog wood in the tank, naturally this required a lot of the decoration in the tank to be shifted around to get into all the nooks now although all the decoration went back into approximately the original positions there was enough disruption in the tank to cause a power shift between the dominant males in the tank. The original alpha loach defiantly lost his position to the challenger for a few days before re-asserting himself and staking a claim on a collection of smaller stones. The new guy is now lording over a single large stone on the other side of the tank. These territories are obscured from each other. Earlier this week i observed one of our females exhibiting clear mating behaviour with the new guy lots of tubercle ruffling and backing down into the scrapes when one of our juveniles happened to swim by, i think the new guy is a little insecure as he felt the need to immediately see off the little one leaving the female all by herself. Clearly miffed by this she upped sticks and took herself over to the other male and started the breeding dance with him. I was not able to see if any eggs were laid we will just have to watch out for the fry in a couple of weeks.
This all took place in the early evening with the lights on.
Well I thought it was about time for an update! Took these pics earlier today 17-11-06, some better than others. Please excuse the snails and snail eggs once again :
In the following pic, you can see the smaller fry from the 2nd spawn in the background:
The following 2 pics are of the lone fry from that 2nd spawning, also taken today:
To be honest mikev, it is near impossible to see any 'mini fences' with the human eye, as these fish really are still very small and are in an unlit tank (receives natural light) which makes it even harder to see detail. All I have to go on are the pics, and this latest batch are with my new camera which has a lot more megapixels than the old one.
If you happen to see them sitting on the glass, maybe you could take an underside picture? I'm curious to see if the fin shape is all the same or different.
Will do. I would have taken some today, but they were being quite stubborn and mostly hiding out of view. I think they have got to that stage where they know to hide once they see the camera approaching....
