Dixon1990 Posted September 29, 2007 Author Report Share Posted September 29, 2007 When do they start looking like black widows? And can in feed them frozen bbs? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted September 30, 2007 Report Share Posted September 30, 2007 Dilute the liquifry in a glass and pur it in. A little and often is the trick. Most people feed too much and cause a bacterial bloom. Live brine shrimp is best if you can get it. Quote Link to comment Share on other sites More sharing options...

Dixon1990 Posted October 9, 2007 Author Report Share Posted October 9, 2007 Im not feeding them bbs as i kept screwing it up. So they are growing very slow i can see a little black on some of them now though, Im just feeding finely crushed flake and liquifry.

Dixon1990 Posted October 28, 2007 Author Report Share Posted October 28, 2007 There are only about 5 or 6 that are about 1cm and the rest (about 10) are still about 6mm and have been that size for ages. Quote Link to comment Share on other sites More sharing options...
Dixon1990 Posted November 12, 2007 Author Report Share Posted November 12, 2007 How long does it take for long-finned black widows to get long fins? Quote Link to comment Share on other sites More sharing options...
caserole Posted November 12, 2007 Report Share Posted November 12, 2007 Stu just read this post and scratches his head and laughed. :-? Come on guy's where's the knowledge on how to breed tetra's. best breeding tank size is 300x600x300, not to small - nor to large. Black widow's should look like adults in 4-6 weeks. They take bbs from the time they are free swimming. If your fry are not growing rapidly it's because you are not giving them enough suitable food. There may be 3 starter reasons you had a low fry count. 1, Your water may be a little to hard. 2, old eggs in female, best to breed them chuck the spawn, condition female and spawn again once full of eggs - in 2 weeks. 3, First spawns of any fish are usually poor or a complete failure, but not always. I pick reason 2, but 1 may be a factor. Hatching bbs is a piece of cake I hatch heaps daily. What do you do Dixon1990 to hatch your shrimp, maybe we can sort it out??.

Dixon1990 Posted November 12, 2007 Author Report Share Posted November 12, 2007 i dont have any brinshrimp at the moment,but when i did i was hatching them in a 1L bottle floating in 25degree water. But i have been feed microworms, frzn bloodworms and tetra granules the last week and they have grown quite a bit more now have about 15 at 1.5cm and their colour is getting a deeper black.

Dixon1990 Posted November 12, 2007 Author Report Share Posted November 12, 2007 I am moving the young tetras to another tank now that is a bit smaller but a more practical shaped tank. The one they are in now is too deep. Quote Link to comment Share on other sites More sharing options...
caserole Posted November 12, 2007 Report Share Posted November 12, 2007 1 of the problems with using a tank to large is the fry have to work harder to find food, unless you put heaps(to much)food in. Hatching bbs in 1lt of water. Add air tube( an air stone is not need ) to keep cysts moving with 2 table spoons (proper measuring spoon)of salt, @25C most should hatch in around 20-24hs. 1 teaspoon of baking soda can also be added to keep the water alkaline. Place no more then 1 teaspoon of b/s in hatcher( if using NZ b/s 1/2 teaspoon) Use or freeze with in 6hours of hatching. Start with a fresh water mix every hatch. Microworms are a good food and black widow fry can eat them from f/swim stage but the fry will never achieve the same growth that they would on bbs.
