Tips on groupers?

[richardhk]

Hello, there:

I wish to receive more information about groupers. Kindly:

1) Advise/suggest what websites would provide such information
2) What is your experience on the growth
period of different groupers?

I have 3 Miniatus( 3.5-4 inches), 5.5 inch
Panther, 2 Honeycomb (same size as Miniatus),
one (3 inch) peacock grouper.

Which grows the fastest?

3) What, how often, how much do you feed them?
4) How many protein skimmers do you have?
5) How do you cope up with the excretions/
ammonia build-up?
6)The miniatus and the honeycomb and
the blue grouper like to scrape themselves
against the rock for the past several weeks.
They eat like horses--from silversides, to brine
shrimps, to small shrimps to mussels, to clams.

Should I be doing something about their scraping, is it sign of ich?

Hope somebody can respond to my question.

Do you have good website about grouper
culture too?

Have had a few panthers in the past, they get huge fast! Try to feed them every other day (if you want to slow growth). When they get big there white turns a light beige color and they become very lethargic. One protein skimmer is enough if it works well. Some sort of mechanical filtration is beneficial , such as filter floss stuffed into a filter chamber somewhere in the system. Lots of water changes will also help, about 1/3 of water volume every 2-3weeks.
Dont worry about ich, they seldom get it and if they do it is easy to cure (on groupers) i.e. copper, garlic,freshwater dip.
Mine use to scrape on the rocks once in awhile and nothing ever came of it.
Got a 5 inch miniatus in my fo tank now and it is one of the coolest and most beautiful fish I have ever owned.
