open brain / sun coral questions

[rossv]

Hello all. For x-mas i got a 6x55w [acronym:a7cfcd18d7="Power compact fluorescent"]PC[/acronym:a7cfcd18d7] light for my 55g tank so ive finally been able to get corals! I got one every few days since xmas and now have a frogspawn, pulsing xenia, trumpet coral, green open brain, sun coral, and a [acronym:a7cfcd18d7="Small Polyped Stoney"]sps[/acronym:a7cfcd18d7] [acronym:a7cfcd18d7="Broken or cut pieces of coral which will eventually grow into a new animal"]frag[/acronym:a7cfcd18d7].

1) The open brain only extends its polyps at night... is that normal?

2) i got the sun coral yesterday and it hasn't extended its polyps all the way yet. I have seen a few start to stick out, but not all the way. Should it be taking this long?

3) also, do you think 6 watts/gallon would be enough for [acronym:a7cfcd18d7="Small Polyped Stoney"]sps[/acronym:a7cfcd18d7] if they are near the top?

ty very much!!!

oh yea, one more question. Whats the best thing to feed the sun coral?

1) This is when my brain feeds also

2) You will need to target feed the sun polyps. Use a 2 litre bottle with the bottom cut off. Place it over the sun polyps and squirt food through the top. Squid, shrimp, scallops, flake; chopped up coarse, not to fine. These coarls prefer lower light as they are not photosynthetic. Oh yeah, you can use a turkey baster to stir up the food when it settles. By doing this there is little waste and eventually all polyps will get a fare share.

3) This is [acronym:b9caf27632="Just My Opinion"]JMO[/acronym:b9caf27632] - Halides are best for [acronym:b9caf27632="Small Polyped Stoney"]sps[/acronym:b9caf27632].

Agreed with the above except...

This will primarily depend on the species of [acronym:dd13852a78="Small Polyped Stoney"]SPS[/acronym:dd13852a78] and the age/stability of the set up. There are many types that will do well under the type of lighting you have. In all honesty the main one to avoid would be most all acroporidae.

[acronym:dd13852a78="In My Experience"]IME[/acronym:dd13852a78], [acronym:dd13852a78="Small Polyped Stoney"]SPS[/acronym:dd13852a78] such as pocillopora, porites, pavona, montipora, stylophora, hydnophora to name a few would do just fine once you and the tank are ready. It's not something to rush into but the possiblility is there..

Cheers
