I feel torches have a range of condition / parameters they can adapt to, and there really isn’t a specific ideal. But they don’t like change.
They will adapt to your parameters but they don’t like constantly having to adapt. Phosphate, nitrates, alkalinity, salinity, temp…this should all be stable and not fluctuating
I think the most important things are flow, lighting, feeding
Flow should be medium. Not like a flag in the wind.
Par should be medium to high. Typically placement mid tank is best. 150-250 par seems to be what most like
They will eat, and I think it’s important to feed them at least weekly. 1-2x a week. Cyclops, mysis, even flake food. They will eat it. Then off flow and baste gently and they will grab it and pull it in
They typically don’t inflate fully the day after eating or while they’d re splitting to fork new heads. This is normal
My current parameters are
Salinity 1.026
Nitrate 6-8
Phosphate .2
Calcium 420-440
Mag 1250-1300
Alkalinity 9.25
For the last year I had phosphate .05 and nitrate 1-3 and alk around 8
I notice no difference between my current values and the values I had for a year before this.
If you look at my tank overall the torches are all mid level to upper mid level on the left or right
And they all get decent flow and are swaying but not aggressively
Some get a little more flow than others. I find it just affects tentacle length. Lower flow seems to promote slightly shorter / thicker tentacles and stronger flow makes longer thinner tentacles. Lower flow let’s then open and expand more. Higher flow makes them blow in a certain direction (see candy cane)
As long as the flow isn’t too low or high and it’s in that middle realm, they will be happy and adapt to it.
Key is just let them adapt and then keep things stable. Keep the off the ground and away from sand. Target feed 1-2x a week to promote growth
I do add aminos to the tanks, Reef energy ab+ At night, 2x a week
I feel it contributes marginally but positively
