blueether Posted November 6, 2011 Author Report Share Posted November 6, 2011 Thankyou for that. Update 6/11/11 (21 days from spawn): today there are free swimming fry :happy2: , well there are fry that bounce off the bottom a few mm then sit there for a while It is quite interesting that some of the fry are now free swimming while others of the same spawn are still in the egg shell. Do they need the help of dad to free them? Quote Link to comment Share on other sites More sharing options...
Stella Posted November 6, 2011 Report Share Posted November 6, 2011 when they are hatching dad will quickly shimmy over them several times, I guess it helps some of them out. I usually find that they all hatch within 24 hours, in the presence of the father. What are you going to feed them? Quote Link to comment Share on other sites More sharing options...
Fruju Posted November 6, 2011 Report Share Posted November 6, 2011 Those are excellent pics!!! Great clarity! Good job on the breeding. Quote Link to comment Share on other sites More sharing options...
blueether Posted November 7, 2011 Author Report Share Posted November 7, 2011 I fear I may have killed many of the eggs as some have started to go cloudy and there is less movement in the others :tears: Hard to tell how many fry are in the tank alive. Have newly hatched brine shrimp, hope they are not too large for the fry. Quote Link to comment Share on other sites More sharing options...
Mikey Posted November 7, 2011 Report Share Posted November 7, 2011 As said above, some brilliant photos of the new additions! I fear I may have killed many of the eggs as some have started to go cloudy and there is less movement in the others :tears: I guess this is why they throw so many eggs out, better chance of some of them surviving... safety in numbers and all that jazz. Good luck with the survivors feeding and getting them bigger! Thanks for updates Quote Link to comment Share on other sites More sharing options...
blueether Posted November 10, 2011 Author Report Share Posted November 10, 2011 Update 10/11/11: I think the eggs need to stay with dad untill hatching... I have had to get rid of about 1/2 - 2/3 the eggs at a guess as they had died. It looks like over 1/2 of the first spawn hatched and a few of the second did as well, but most of the second spawn have died. A few of the fry have died and a few more look deformed/bent... too long in the eggs not able to get out with out dad? At a guess I would say that there is about 20 or so good looking fry free swimming, some very well. Quote Link to comment Share on other sites More sharing options...
danval Posted November 10, 2011 Report Share Posted November 10, 2011 Hey blueether. What sort of camera do you use. Cheers Quote Link to comment Share on other sites More sharing options...
blueether Posted November 11, 2011 Author Report Share Posted November 11, 2011 Hey blueether. What sort of camera do you use. Cheers Nikon D40x and the macro shots were with a 36mm and 36m + 20mm macro tubes Quote Link to comment Share on other sites More sharing options...
blueether Posted November 12, 2011 Author Report Share Posted November 12, 2011 Update 13/11/11: As of last night there are 25 fry still alive, and I guess I lost about that many in the last week. They seem like hard little critters to keep alive. Also as of last night the male Cran's bully is guarding another clutch of eggs, and is today trying to entice yet another female in to his man cave. [Edit] Photos of them spawning (sorry about the distortion, photographed at ~50+ deg through 10mm of glass): [Edit 2] A pic of the second spawn that only a very few hatched from, most died without dad looking after them: Quote Link to comment Share on other sites More sharing options...
Mikey Posted November 14, 2011 Report Share Posted November 14, 2011 Also as of last night the male Cran's bully is guarding another clutch of eggs, and is today trying to entice yet another female in to his man cave. Sheesh... you have a busy boy there! What are you going to do when you end up with a couple of dozen happy healthy bullies? Is it a man cave if there is no tools or entertainment? I can't see the tool racks or TV screens in the photos :rotf: Quote Link to comment Share on other sites More sharing options...
blueether Posted November 14, 2011 Author Report Share Posted November 14, 2011 Sheesh... you have a busy boy there! Four spawns in four weeks is not too bad What are you going to do when you end up with a couple of dozen happy healthy bullies? I hope I get that many, I'm finding it hard to keep them alive :tears: I'm hoping that these net two spawns have a better survival rate than the first two. If I get too many I know someone that wants a few, and I could always try trademe or the LFS Is it a man cave if there is no tools or entertainment? I can't see the tool racks or TV screens in the photos :rotf:Plenty of entertainment, just a lack of tools Quote Link to comment Share on other sites More sharing options...
Devon Posted November 15, 2011 Report Share Posted November 15, 2011 They'll be feeding on 60-100micron zooplankton, which is bloody small I bred redfin bullies, and couldn't bring any of the fry to adult hood due to lack of food. I tried using green water, which had all sorts in it, micro algae's, tiny zoo plankton but to no success. Commonly the fry will travel out to sea for a short period of time, feeding, before then returning back into the tributaries. However, Crans and Commans are known to reproduce, successfully in ponds, so do not necessarily need to feed on whatever it is they're feeding on at sea. Try collecting pond water, culturing it in a larger container and placing eggs in that, probably your best bet! Quote Link to comment Share on other sites More sharing options...
blueether Posted December 11, 2011 Author Report Share Posted December 11, 2011 By the 20th November none of the first fry that hatched were still alive Update 11/12/2011: Today I decided to change the tank stand to one I had made in the last few week so firstly caught the two bullies that were looking after eggs and placed then in a ~7l plastic bin with their rocks, then proceeded to empty the main tank out so I could move it. Some time later while awaiting a helping hand to move the tank I noticed that the next spawn had hatched :happy1: fantastic timing, I new they were nearing as it's been 3 weeks since the spawn. The two dads are still in there with the rest of the eggs and I have placed some pond weed in there for the fry to hide in, but the two dads look to be well behaved and aren't even looking at the fry. Here's hopping for better success than the last hatching. Quote Link to comment Share on other sites More sharing options...
Mikey Posted December 11, 2011 Report Share Posted December 11, 2011 Heh, that is nice timing. Hope you have success this time! *crosses fingers* Quote Link to comment Share on other sites More sharing options...
blueether Posted December 12, 2011 Author Report Share Posted December 12, 2011 Nope, most died over night and today, as did most of the eggs Lack of o2? too warm ~18-19 deg? (were at 16 in main tank) Put the remaining ones in the 1/2 wine cask on the back porch, see how they do if any survive... Quote Link to comment Share on other sites More sharing options...
