Diamond Tetra Spawning?
I just got ahold of some Diamonds yesterday ... and am wondering if they are already spawning. They are adults, and the males are clearly chasing the females around and swimming right up close to them.

Not sure if it's spawning or harassment, Diamonds are suppose to be peaceful so I'm inclined to think spawning.

I tried to make a video, but the point and shoot isn't so good at that, and of course when you stand in front of the tank everyone acts all innocent. Everything is horribly washed out too, poor color balance on the camera.

I worry about the poor females. Their are 10 Diamond's total, about half male half female.

Well Tetras do a lot of chasing and racing the length of the tank... certainly my Congo Tetras do this with my Rainbowfish. No harm is done ever.
With your tank being so large and newly planted there is not a lot of cover, some hiding spots but Tetras really are not the hiding kind of fish really.
Maybe some more floating plants? Or even float some plastic ones for awhile while you wait for the real to grow. Just a suggestion.

Well, it's more than just racing. Males are displaying at each other and charging. If a female swims buy they get chased. It sounds like they're spawning but I wasn't really sure. They are not biting each other at least.

You can't really see it in the video, but I do have Water Sprite, Dwarf Water Lettuce, and Amazon Frogbit floating in the tank.

There are also a couple stem plants and java ferns that escape my planting and refuse to stay put >.>

I agree more floating plants are needed to reduce that light, but the Water Sprite especially will spread once it is settled, so the lack of adequate cover now will soon resolve itself.:-) And this will help the fish.

Characins should be like this, depending upon species. Males will challenge each other, and drive the females particularly when they know she is ready to spawn [those pheromones again]. Also, in new surroundings it is naturally for fish to over-react, although sometimes it is the opposite and they hide. That too should settle. But this is a somewhat active species, I have maintained them and they spawned many times, I even had a few fry survive in the plants. When they are ready to actually spawn, the male will drive the female into plants.

I don't think the females are ready to, they are far too skinny looking. But I have seen the males driving them towards the plants in the back. When the males challenge each other it's pretty humorous. Really reminds me of Bettas when they flare if you look at them.

I've noticed this behavior twice though. Both times after feeding frozen foods (Blood worms once, brine shrimp the other). I'm wondering if that's triggering a response from the males.

The females are beginning to show some girth though. The population is backwards unfortunately, 6 males 4 females. Poor girls =o

The Water Sprite is growing, the Dwarf Water Lettuce and Amazon Frogbit are growing amongst the Water Sprite. It looks like two floating islands in the tank. The Dwarf Water Lettuce is definitely growing much quicker than Amazon Frogbit. I'm picking off the new Water Sprites to hopefully speed up its propagation.

mass feedings should be made with high quality foods should be made as to ensure there is not over competition of foods and for the females to achieve a gravid diamonds spawn in very bright light and i personaly use a large amount of java moss located in the bottom back and sides of the aquarium not to mention attatched to the wood in the tank as well.are you going to try and take the eggs and hatch tem seperately? or are you going to just try your luck and see if they hatch out in the tank.either way i would resomend some moss. :)

I'm not going to actively try to spawn them, I wouldn't have the means to support growing them out.

I'd love some Java Moss ... if I could find it. It's not sold in any stores around here, and everyone on ebay wants $10+ for a tiny amount.

if there was a way i would pretty much give you some.i would presume without a plant as pinnated as this and as dense there would be little to no chance on getting fry.not only as a defense from the parents but to supply them with the micro foods as well.
