yuma in the shade question

[eaglesrx]

Hello,

just curious; how long does everyone leave their yuma in a shaded area before switching to another, brighter area when introducing the yuma to the tank? Or does anyone always leave it in the shaded area?

Thanks!

I usually do not leave it in a shaded area. But my lighting is not very powerful, so the potential to bleach it is very low. I think the goal is to acclimate the ricordia to your own lighting, not necessarily to shade it completely. That is why it is recommended to start at the sandbed and slowly work your way up. You have to look at how the LFS is storing them, if they are under MH, and you have low powered PC at home, it is pretty safe to put them in your tank without light shock. If your LFS keeps them under VHO, and you have some 400w MH at home, you better start very low or shades.

I agree with the above. My lighting sucks (2 x 65W PC... 65W of which is actinic) so I just start mine out on the bottom corner and work them towards the center over a couple months, or just leave them where they started and they do fine. Depends on each yuma it seems.

some yumas like the shade. I have 1 in the shade and it is doing very well. They are all different. I keep all of my yumas at the bottom of the tank and the florida at the top

thanks everyone for your input.

My plan is 1 month in the shade (unless it shows symptoms of not responding well) and low flow. Then, I'll gradually move it out to non-shaded, bottom areas of my tank. These yumas seem to more unpridictable than some SPS!!!

Did all of you transition the location based on flow, i.e. low flow to moderate flow? I know yuma's in general should be low light, low flow. However, I have several spots at the front of my tank that get a decent amount of indirect flow (i.e. flow crashes off my glass and moves down to the sand).

Thanks!

Indirect flow should be fine as long as it isn't strong. Mine are in medium-low indirect flow and they are doing fine.

shoot me now, but I have not acclimated any of my yuma. I put them in direct lite and they are doing wonderfull. I have 150w 20k M/H. They are all in the sand bed except for the one shaded by my frogspawn above it.

hey currentking,

how long have you had those particular yumas? They all look fantastic!!

thanks!

ive had them for a couple months, except for the pink one just bought last week. Im finding the pink one need very little light. It get very big at night then shrinks during the day when the light hits it
