I will try.
The two ryukins were picked up and brought home. I isoed them in the same tank, thinking they were both males. The move and stress were enough to make the ripe female drop eggs. I quickly dropped in as much matting as I had. I then had no choice but to move the parents from their bigger iso tank to a smaller one.
I then split them up the tank was really too small for two such large fish, and I did not want him picking at her. She only had a few hundred eggs and I was not going to push matters. (I do not feel that I was responsible for this breeding - I did not prep the fish - they came that way....)
The eggs were kept in a 25 gallon tank with a seasoned sponge filter. The water was treated with Acriflavine ( I cannot get Methlene Blue!!!!). Some fungused eggs were removed on day2.
The tank was kept at an even 70F - being long finned fancies, I upped the temp from the usual 69. I could not easily hit 71F and do not trust a heater to do the job as perfectly as I required. I heated the tank with a 60 watt light bulb that was under the tank base - no light - just rising heat.
At 4 days - almost to the hour, the babies hatched. After remaining stationary for approximately 30-36 hours, they were up and hunting. I fed live baby brine shrimp, but quickly ran out. I then fed frozen baby brine shrimp until I got my shrimp hatcheries up and running more efficiantly. I bought decapsulated shrimp eggs - grade A - they hatch out well with no shells to constipate/kill the fry.
The babies are still kept at 70F. It is difficult to raise the temp in any way - I do not trust my smaller heaters in such a little amount of water. It is the dead of cooooold winter right now - Negative 7F last night - and the house temps (64F) just do not allow for very warm water at this time. I have the water at 8 inches deep. I syphon the waste out daily (about 1 gallon) and replace about 1.5 gallons back. I am slowly adding more depth tothe water. I am still filtering with just an airbubbler in a sponge filter and the water is still staying in good parameters.
I am feeding baby brine shrimp approximately 6 times a day. They always have something swimming in the wtaer to eat. The babies have doubled in length and size in 8 days.
I have a few with obvious bent backs, and a couple with strange looking double tails. But they are really too tiny to determine exactly what may be "off" so I will wait.
I read that long finned, deep bodied fish need live food to grow the body depth necessary to carry the heavy tails properly. So I am intending to stick to live food for quite a while on these little guys. I have to get past the time when my hubby comes home and finds little pop bottles of shrimp bubbling on the kitchen counters or..... microworms brewing in a box! (ewwwwh!)..... Perhaps the frozen foods will be more acceptable to him. We will see....
I will keep you all posted.
