is 400w to much for a RBTA

[Alex 220gal]

I have 3x-400w MH in my set up
I had one for 3 weeks now and he keeps moving in the tank. He has not opened 100% since I got him. The last 4 days he is MIA and I dont want to tear my tank apart looking for him(PITA). He leaves this slim ring behind? Is this normal?

If he dies will it crash my tank if I dont get him out?
I have a 220gal filled with rock so it might be hard to find him

I am down grading my lights soon but not for at least a week

what should I do?

I had one in my tank with a 400W Radium.

I had it on the bottom and he kept moving closer to the light and now MIA????

 

[Alex 220gal]

still missing, if dead will he mess up tank?

 

[NirvanaFan]

how big was it? It shouldn't mess up your tank unless it was large.

 

[Alex 220gal]

6" wide

Do RBTA like high alk?

I am having a problm dropping my alk and maybe this is why?

Did you acclimate it to your lights? That is a lot of light, not enough for it to handle, but would be too much all at once.

As Todd said, acclimation is key. The only light too bright for a BTA is a light brighter than the tropical sun :eek2:

I did, he stayed on bottom then went closer to the light a week later, then MIA?

How did you acclimate it, and for how long?
