I tend to add a ton every day for the adults and babies and turn off the filter down for 8 hours ... no overflow it's a 12g fluval ...
here is a baby eating brine still floating around after 6 hours ... temps are at 75
these are the only types of food dwarfs eat ... I enrich and feed adult brine and babies ... also have cope pods and Amphipods in the tank .... problem is the dwarfs don't eat the adults, and the adult Amphipods are carnivorous and eat fry.
I'll see if I can get Rotifers for the next ones
"Brine shrimp, Artemia Sp.
The most common food offered to seahorses and also probably the worst. Many fish stores recommend feeding this because as a live food, a lot of seahorses will react to it and eat it. However, there is virtually no nutritional value to them, and because seahorses have a short digestive tract, they can not even make use of the little bit nutrients there. Seahorses fed only this will slowly die of starvation, sometimes over a period of months. There is some value to enriching them, although not enough to be a staple of the diet. They are often refused as well because they do not behave like "normal" shrimp which are part of a seahorse's natural diet. Their swimming habits often confuse seahorses, leaving them often to entirely ignore the brine shrimp.
Baby Brine Shrimp, Artemia sp.
Unlike Adult Brine shrimp there is SOME nutritional value to newly hatched baby brine shrimp. They have a nutritious yolk reserve to allow them to hatch out and survive the first twelve hours until they develop a complete mouth and anus. It is when they first hatch that they are still at their most nutritious and should be fed. Decapsulating the cyst before hatching (removing the shells) is recommended so it takes less energy for the brine nauplii to hatch, and are therefore more nutritious because they've used less of their food store. Brine shrimp can also be enriched for 24 hours before feeding. Baby brine shrimp is the normal staple for dwarf seahorses, and is often used to feed seahorse fry.

Rotifers
Saltwater rotifers are microscopic organisms feed to seahorse fry that are too small to take brine shrimp at birth, and for supplementing the diet of adult dwarf seahorse. They are easy to culture using phytoplankton, yeast, special rotifer food, and even v8! There are a few different species and strains available in aquaculture, and choosing larger ones is usually better for seahorse fry.

Copepod
Copepod
Copepods
Tiny crustaceans, most roughly the size of new born brine shrimp. They are the best food for seahorse fry and dwarfs, but are not easy to culture and depending on their swimming habits, may not be noticed by some fry. There are three kinds of copepods generally used for feeding seahorses, harpactacoid, cyclopoid and calanoid. Harpactacoid are the easiest to culture, but they prefer living on the surface of objects, and thus do not always attract the attention of seahorses.They can be gathered from aquariums at night when they are most commonly found on the sides of the aquarium. Culturing just requires a container with an airline set on low, and crushed flake food. Calanoids swim in the water column which makes them ideal for seahorse fry and dwarves. However they are not easily cultured. Most used for seahorse food are caught directly from the ocean. Cyclopoids (cyclops) are found in refugiums occasionally and fed out. They are predatory, so culturing is probably not an option."
