Zebrafish
AM Feed

PM Feed
- Live brine shrimp that was collected during the morning is fed in the afternoon. If there was a low collection number then the Ocean Nutrition Brine Shrimp Plus can be used

- 30 gallon tanks have some poured in a little at a time up to 15-20mls
Sand Lance
AM Feed
- In a 250ml glass beaker containing 3 cubes of brine shrimp, ~3”x2” chunk of mysis shrimp, defrost with salt water from their tank in front of brine shrimp lamp

Horseshoe Crabs
Notes: New arrivals will not have an appetite due to stress so there is no need to feed a large amount
- In a 100ml beaker containing chunks of clam meat defrost with salt water from their tank in front of brine shrimp lamp
- Remove each crab individually to hand feed, placing the meat directly on its mouth
- Turn each crab over and
- Hold each crab either by placing both hands on the sides of its shell or by holding on to the front edge
- As each crab eats place them on the shelf
- Offer a couple of strips to each crab
- Once each crab has finished eating they can be placed back in the water

Cichlids
- Cichlid Flake is fed during the AM feed
- When feeding flake food give each fish about a small pinch of flake
- If still hungry give one more small pinch
- Krill is fed during the PM feed
- Cichlids have a large appetite and will be able to eat more food than defrosted
- In a 100ml beaker containing a ~2”x1” chunk of krill defrost with Cichlid top-off water in front of brine shrimp lamp
- Once defrosted feed each fish by pipette until full or no more food is left
