Ira Posted April 4, 2004 Author Report Share Posted April 4, 2004 Just an update, still got heaps. Fed them their first meal of brine shrimp today. They now look like a little gold ring followed by an irridecent blue dot with a big orange blob underneath. So, at a little over a week old they're big enough to eat brine shrimp. How long will the BBS survive in freshwater? I kinda expected they'd be dead in a couple hours but it's been almost 3 and they all seem still alive and well.

Matthew Posted April 5, 2004 Report Share Posted April 5, 2004 BBS live around 6 hours in freshwater I believe. Quote Link to comment Share on other sites More sharing options...
hevalump Posted April 6, 2004 Report Share Posted April 6, 2004 question: why do you have to lower the water level? Quote Link to comment Share on other sites More sharing options...
Caryl Posted April 6, 2004 Report Share Posted April 6, 2004 Something to do with the development of their labyrinth organ I think hevalump. Quote Link to comment Share on other sites More sharing options...
Pegasus Posted April 6, 2004 Report Share Posted April 6, 2004 AsCaryl says, plus the fact that these fish breathe from the surface, which they do constantly on and off.. all day.. all night, so having the water deep would cause great efforts for the young fry to keep swimming to the surface.

Ira Posted April 6, 2004 Author Report Share Posted April 6, 2004 Mine seemed to always be at the surface from day 1. The only time I've seen them lower is when I pull the blanket off to have a look in the tank, but I think that's because their startle response is to dive. It's only recently that a handful have started going deeper. They're starting to look like fish now. I had a dream about my fry last night...They'd all turned into guppies, pissed me off...hahaha.

Caryl Posted April 6, 2004 Report Share Posted April 6, 2004 I thought that Pegasus then wondered why since don't the young stay in the bubble nest at the surface, or is that only for a short time? Quote Link to comment Share on other sites More sharing options...
Pegasus Posted April 7, 2004 Report Share Posted April 7, 2004 It's only the male that keeps them attached to the nest, and as far as I know, they have no "homing" instinct. Like any child, they tend to wander off, and as the days pass they will become more adventurous and the water level can be increased gradually each day if needed. As above, once they are free swimming there is no need for the male to be in there.. Some of my last batch are now about 48mm long and just look like "Mini Leeri's" Quote Link to comment Share on other sites More sharing options...
Ira Posted May 3, 2004 Author Report Share Posted May 3, 2004 The count is up to 125 fry. Just counting them as I move them to new tanks. I moved 25 to a small planted tank in the bathroom. This one.... And they exploded! In a week they've grown to about twice the length of the rest of the fry. They're up around an 3/4-1" I think now. So that made me decide to hurry up and set up one of the other tanks in my sleepout, a 200ish liter corner tank with some plants and I've put another 100 fry into that tank. Seems maybe they were too crowded in the original tank. All the water parameters were fine so I'm guessing they were growing slower due to more competition for food? Anyway, it looks like there are at least as many left in the original tank as I moved to the new one. So I think there are at least another 100 uncounted.

suemack Posted May 4, 2004 Report Share Posted May 4, 2004 cool....that's a reasonable number of surviving fry Ira. What's the plant in the tank? don't think I've seen that in the lfs up here? sue Quote Link to comment Share on other sites More sharing options...
Ira Posted May 4, 2004 Author Report Share Posted May 4, 2004 No idea, some sorta sword. I think Caryl had a bunch in a picture of her tank, one of a rainbow. maybe she knows the name? Quote Link to comment Share on other sites More sharing options...
Caryl Posted May 4, 2004 Report Share Posted May 4, 2004 It does look the same Ira but it was given to me and I have no idea what it is. I thought it was a crypt :roll: Quote Link to comment Share on other sites More sharing options...
Ira Posted May 5, 2004 Author Report Share Posted May 5, 2004 I thought crypts were usually much longer narrower leaves and more vertical? Anyway, it's a nice plant whatever it is. Quote Link to comment Share on other sites More sharing options...
Rob Posted May 5, 2004 Report Share Posted May 5, 2004 Looks like Cryptocoryne pontidefolia (sp??) Quote Link to comment Share on other sites More sharing options...
Caryl Posted May 5, 2004 Report Share Posted May 5, 2004 That's what I thought Rob but am not too up with the various plant types Quote Link to comment Share on other sites More sharing options...
Ira Posted May 5, 2004 Author Report Share Posted May 5, 2004 Looks like you're right, sorta, rob. Looks like they're Cryptocoryne pontederiifolia Looks like they can grow emersed too...Might give that a try sometime. Quote Link to comment Share on other sites More sharing options...
