Corals, which can i have?

[sniggib]

Hi, my name is matt and im new to the hobby. Ive been running my 20 gallon tank for about 3 months and have one red perculer clown, 14kg of live rock, 2 powerheads 1200, aqua medic bioflotor skimmer,8 hermit crabs (red legs and micro blues), several snails and one piece of coral (cant remember name). My lighting is 1 x 420 actinic and 1 x 10,000 k flourescent. i am hoping to build up my coral stocks and am wondering which corals would be suitable for my tank??? also some sort of greenery i.e seaweed. does anyone have any suggestions of what type of things i can keep?

Matt,

What type of lighting is it?

Power Compact (PC)
Flourescent (then is it Normal output (NO) or high output (HO or VHO)

I'm guessing that bassed on your description it may just be a normal flourescent fixture... if that's the case you are going to want to look at lower light softies... Leather(s), zoos, polyps...

As for algae chaeto is probably the best as it is the easiest to maintain.

You may want to consider a different lighting fixture which might give you more flexibility.

What is the wattage on those lights?

[sniggib]

i think that it is just a normal flourescent light. If i wanted to keep other types of corals then what would you reccommend upgrading lighting to?

[sniggib]

not sure about wattage but i will find out

I would do some reaseach, but for a tank that size a PC fixture, or a flourscent HO (VHO or T5) fixture would be fine for starting out.

think 18 watt but not too sure. has to be under 20 watt as buld holder thing only goes up to 20 watt
