Angelfish laying eggs
Amber, An air-operated sponge filter would be best (and safest) for Angelfish fry. While a power filter having its intake covered with a sponge barrier may work with those filters having a control to adjust/reduce its flow, without such a provision the fry can still be sucked up against the sponge material when venturing too close if the flow is too strong.
Probably just a slip of the the tongue (finger), but while newly- hatched brine shrimp are available frozen (no, they won’t become alive when thawed) as a convenient method to feed them to fish fry, brine shrimp eggs do not come frozen. The serious Angelfish breeder intent on raising this species should hatch their own baby brine shrimp for best success as this is agreed to be the most nutitious food one can offer fish fry — with micro-worms being considered the second best fry food. For the occasional breeder of fish, a fai amount of success will still be had when feeding frozen newly-hatched brine shrimp to their fry, provided this food is kept in circulation by mild aeration (via an airstone), which imparts some “action” to this food as if it might be alive; this food, when settled to the bottom, is not as eagerly taken.
Brine shrimp eggs are bought in a container off the shelf, to be hatched in a solution of salt water. Herein lies the problem when confronted by the smaller or occasional breeder of fish requiring this as their first food. The longer brine shrimp eggs remain on the shelf, the less fecundity can be expected of the hatch as the hatching rate (percentage) diminishes with time, especially at normal room temperature (not to mention summertime temperatures). The most convenient and economical packaging of brine shrimp eggs the infrequent breeder can buy is a small vial of an ounce or less; slightly larger amounts of up to a 3.5 ounce can is also offered. Unfortunately, as this packaging is aimed for the infrequent breeder of fish (serious breeders buy brine shrimp eggs in larger quanties of 1 pound cans), these smaller amounts often remain on the shelf for extended periods of time, often resulting in very poor (or no) hatch.
For this reason, it must be decided on how much fish raising one wants to enter into when condidering how large of a container of shrimp eggs to purchase, unless its decided just to take a chance on th smaller quantities hatching rate. Larger quanties will last a good amount of time provided they’re refigerated. Ray
