I am currently breeding Zebra Danios and I have a couple of questions. I found a really good site but then it turned out that modelling my fry's life cycle is not even close to his.
My first two fry are 24 and 22 days old, their eyes have become much bigger, they are wider, about 2mm longer than when they first came up and their internal organs are bigger and pinker. I fed them infusoria (3 drops 3 or 4 times daily) until yesterday when I started feeding them freshly ground food. They are living in a 0.866 gallon tupper ware container at the moment and I'm wondering if this is a normal rate of growth or are they growing slower than this person's model because they were in a 10 gallon tank and they were fed grindalworms, microworms and newly hatched brine shrimp as well? According to that guy's model my fish are around the "7 day old" mark - 5mm with a neon stripe. Has anyone had any experience with breeding zebra danios than can help me with that?
Secondly, I have 165+ fry in a 10 gallon tank which is about 3/4 filled with 2 inches of marbles on the bottom and a sponge filter. I started feeding them infusoria yesterday with meals of 6-8 drops 3 or 4 times a day. I am not sure if I am feeding them enough, is there any way to know?? I bought a brine shrimp hatchery and I'm going to set it up on Wednesday night to have it ready for Thursday morning feeding. Has anyone had any experience with those?? The model I was following says that if you do everything properly than at day 28 the fry should be moved to a growout tank of ~50 gallons. My early 20 day old fish are certainly not ready for the bigger tank because their mates would make lunch of them. I only have a 23 gallon tank that is currently occupied by 10 adult fish available and I may be getting another 10, a 5, and if no goldfish survive the summer than another 5. So is it the size of the tank that matters or the space? Adult fish only grow to ~1.5 inches.
Any advice would be appreciated!
