spawning tricinctus!

day 7 update
today i noticed the fry actively hunting copepods in addition to rotifers. the copepods are larger and much faster than the rotifers, actively swimming through the water column.

the last 48 hours i have been showing ammonia on my ammonia alert. i did a 50% water change yesterday, i will probably do another today.

i am down to about 16 fry. i suspect i actually had closer to 30 fry by the end of day 4. and have had closer to 16 for the last three days. i am not seeing any bodies though which is interesting.

i have been largely unsuccessful with phyto. my batch of nanno is doing just fine, very dark green and healthy. but my second and most likely last attempt at tetra failed. i have one more sample of iso coming this week i will try my hand at. i will probably stick to using solely the RGcomplete, after a pretty good discussion on this thread:

http://www.reefcentral.com/forums/showthread.php?p=21920511#post21920511

it appears to be working very well. i feed about 2 mL of RG complete to each rotifer bucket and 1 mL to my fry tank twice a day. i am also adding about 1 mL of selcon to my rotifer buckets once a day.

things to comment on:

where is the ammonia suddenly coming from?
could my sponge filter be filled with organic matter and overwhelmed?
i may have far too many rotifers in with the limited number of fry, could this be the culprit?

my temperature is running consistently at 86 degrees. this does not seem to affect the fry. anyone notice problems keeping the temperature this warm? they are certainly not starving so the higher activity level and metabolism created by this warmer water shouldnt be an issue, or am i completely wrong?

what are the thoughts on utilizing the same tank for 1 day old fry and soon to be 9 day old fry?

selcon to the rotifers? useless?

the ammonia could be from to many rotifers, or to much food, I have never really had any issues with ammonia till meta right before I added my filter but I would also syphon out the tank 2 times a day. when was the last time you cleaned the filter?

I can't say much about the temp as I keep my fry at 80-81.

do not use the same tank for 1 day old fry as 9 day old fry, the little bit of diffrence may not seem like much but the new fry won't survive.

if using rgcomplete there should be no reason to add in extra stuff, if using home grown phyto then I would add the selcon to the rots.
 
day eight

here are the little guys in moving pictures! theyre tireless. most are very developed, at least one looks like it hasnt changed since day one. some have lots of yellow in their tails. there is lots of detritus to suck up throughout the day now that wasnt present before yesterday. i tried a small amount of otohime A this morning. i got the impression they could smell food in the water, as their activity seemed to pick up. but there was very little interest in the powder now floating on the water.

question for today, as you can hear in the video, my air pump is absolutely obnoxious. throw out some other large air pumps that are much quieter....do they even exist?
 
I have been using the cheap ones from walmart and they are dead silent. Ill get the brand name when i get home from work.
 
The brand air pumps I've been using are called aqua culture. These have worked well for me and silent compared to my whisper pumps
 
There are 13 of them as of tonight. At least five of them are very developed, a few still remain almost unchanged since they hatched. I tried another feeding of otohime A this evening. There seems to be interest, particularly if it is dropped into the bubbles and mixed into the water column, as opposed to just floating on the surface. No definitive signs of actually eating it yet though.

Another observation: there are no more little copepods skirting around the waters surface and glass. They must be delicious. Two days ago I purchased some tiger pods from reeds mariculture, poured them in a bucket with a bale of chaeto and some phyto and as of today there certainly seems like they have been reproducing. This will hopefully supplement the transition into dry, prepared foods.
 
I dont think the otohmine is really for the fish to eat but mearly just get them accustumed to dry foods. At least i think i read that somewhere from reeds. Also ime my fry i have not seen them eat it either but when i switched to the larger fry dry foods they seemed to go right for it
 
thank you!

mikey, what do you consider the danger area? considering it appears only one of the fry has reached metamorphosis and the rest are in varying stages of development i would say until they start eating prepared foods for me....they will remain in THE DANGER ZONE!
 
day 10

i believe at least one fish has reached metamorphosis. this fish is black, has a distinct stripe in its midsection, and has started the trade mark bob up and down swim. it has also adopted a suction cup as its anemone.

here is a dramatic photo stream:








and a very short accidental clip:

i have another nest hatching tonight. my hands will be full these next few weeks. but i certainly think i can get more than 13 fry by day 10. my goal is to keep closer to 50 going.

and with a chrysopterus spawn seemingly imminent as well....im going to have a garage full of ten gallon grow out tanks. my girlfriend will be so pleased.
 
Do you use nsw in the fry tanks or parent water? I have heard people get better results with nsw but i havent tried it yet, maybe next time. My 1st try i only had 30 but my second batch is around 100 both using parent water though
 
good morning marina! i believe the pictures are a bit deceiving. one more day of development and things look more how theyre supposed to this morning. there definitely are stripes (complete from what i can see). and now, on day 11, most of the fry are dark in color with what appears to be vertical stripes. ill get some more pictures up. this particular little guy still hasnt left his beloved suction cup.

the pearl eyes could be interesting....but i suspect its just the light reflecting off the top of their eyes through their scales and not reflective pigment.
