So are you saying that they all had birth defect?
No I am not
cause I was not there
I explained how seahorses work
and the parents need to be STRONG and HEALTHY to give birth to strong and healthy babies, as you explained the father was not doing good after, so that shows the babies are not the healthiest of the bunch. a healthy Reidi will get prag. again within 24 hours of giving birth. and 14 days later will pop.
now about H.Reidi, you are actually trying to breed one of the HARDEST type of seahorse. so dont feel bad at all. now reidis as babies will not hitch to anything, and they are too small to accept BBS, they need to be started off with rotifers ! 99% of times. now they are very week, and need to be fed at least 10 times a day, with rotifers which are enriched with Beta Glucan to give them energy, after a couple days, they can be switched over to BBS, and then after first week brine shrimp couple days old and enriched.
now what have you been feeding your fry ?
"Reidi gave birth 4 days ago while we were out, so I only managed to catch what I saw after, which came to about 40 babies. I put them in a rearing tank which goes into the parents' tank, with slits to allow communication of the water."
they give birth to over 200 usually, and the fry are REALLY sensitive to Hydroids and more ... so their sting can be lethal. jus the time elapsed between you getting them out could be enough to paralyze some .
connecting it to your seahorse tank is not recommended.
also a nursery for seahorse should keep the seahorses rotating around the tank for at least 2 weeks ! the fry should not be able to swim where he wants, flow should move it around and around so it wont get stuck to surface nor sink to the bottom. the flow should be provided with a rigid air tube, with BIG bubbles so seahorses wont digest the smaller bubbles....
seahorse.org has ALOT of really good info which you should read.
just sharing info
it took me like 7 tries to finally start raising the fry.
and lastly : "I am no expert, just been keeping seahorses in the last year after the first year of reef keeping. This is my third pair of seahorses, but is the first pair of H. Reidi. The previous ones were H. kuda, then tiger tails. I think the babies simply gulp air, being unable to control their own movements when they were weak and small, and since the small air bubble in their throat becomes like a buoy, they then could not move around to eat! So they starve to death..."
what happened to the H.Kuda and tiger tails ? those are strong ponies ! seahorses require alot more care and have specific needs. are they Wild caught or captive bread ? have you de-wormed them ? what do you feed them ?
