It not surprising to hear the Condy is not doing well. They need fairly high light levels. I would recommend a VHO
or T-5 fluorescent set up. They have great color, are generally moderately priced, don't produce too much heat, and can support a wide variety of animals. A general rule of thumb is 3-5 wpg
, although it can vary depending on the type of lighting, etc. You will need to be on the higher end of the scale to properly support an anemone.
If you have a canopy, can DIY a canopy (it's not too hard or expensive) or can suspend the lighting above the tank some other way, retro-kits are probably the lowest priced option. Take a look at these for some ideas-
As far as the Condy goes, what are your water params? Do you target feed it? If so what and how often?
