Pond Boss Forums FISH & FISHING Sunfish-Including Largemouth and Smallmouth Bass Bluegill spawn in 100 gallon aquarium.

I think the algae is ingested as incidental items along with primary food such as large protozoa and rotifers. They can grow quickly so they do not stay eating each size item for very long. Some fry species have a difficult time inflating the air bladder if conditions are not correct thus mortality can be very high at this time period.
