Rotate food type each day: Hikari frozen mysis, Hikari frozen brine shrimp (regular and algae enriched), PE Mysis, Rod's Food blend

Initially fed twice daily but at the second feeding they were disinterested and a lot of food just sank to the bottom while they hid at the back of the tank. Changed feedings to once daily, as much as they will eat.

Spawn Details
|
|
Pre-Spawn Behavior: |
The day or two before the spawn takes place they eat more than usually and they make a lot of "jerky" movements around the tank that I don't normally see.
|
|
Spawning Behavior:
|
The day of the spawning, male and female line up side by side, quivering and shaking for about half a minute, then they separate for a longer period of time. This repeats over and over, sometimes for a few hours or sometimes all day long. Twice they've spawn during the middle of the day and once after the lights went out.
|
|
Post Spawn Behavior:
|
They usually separate for a little while, and then the female comes back and makes several more jerky movements around the male, similar to the pre-spawn behavior but more focused. She continues following him around the tank, making sudden movements but staying close by.
