I have 8 adults. 5 females and 3 males. We had dozens of babies this past year and hundreds more eggs coming. I did have a high mortality rate with the eggs though. It is extremely difficult to keep the water temp low in Florida during the summer. Anything above 75 and it definitely has an affect on the eggs (and babies/adults). Does the lighter egg have a yolk? Usually when they are light colored like that they are empty or spoiled. I started my skates with superba krill and pe mysis. Rarely did I have to use live.
