A few things happened today. First, in taking out some empty egg casings, I accidentally released an alevin into the main tank. It quickly went down into the gravel to hide. I had to put a mesh netting around the filter intake to avoid having it sucked into the filter.
Second, the pH level seems a little high (8.2) and that has me concerned. I guess we are going to have to treat the aquarium with something to lower it. Ammonia and Nitrite still holding at 0 ppm.
Finally, the hatching baskets might have be let down tomorrow. With all the eggs now hatched, the fish will be needing more room. We will make that decision in the morning.
What is causing the pH level elevation? When you say "eggs to fry" what exactly do you mean?

Most fish thrive in a pH of 6.4-7.8. The goal is to have the pH level as close to neutral (7) as possible. The accumulation of ammonia due to waste products might be encouraging a slight rise in the pH level but as long as it stays around 7-7.5, I think we will be ok.
ReplyDeleteOur "trout" arrived as eggs in the eyed-stage, meaning that they were developing normal and the eyes had become pigmented and are visible. After about a week, the trout begin to hatch as sac-fry or alevin. These have their yolk sac still attached. After a few weeks they absorb the sac and become free feeding immature trout known as fry. They will be called trout fry until they are about 2 inches or so in length when they become a fingerling.
