Informational: My fish are fighting! ........Help!

Posted 08/11/2015 at 01:16 PM by Sk8r

Informational: Help, my fish are fighting...!!!
The old freshwater designations of aggressive and community don't work well as marine concepts.

Marine fish are almost all (including the oblivious-to-the-world mandarins) capable of killing another fish, under one of two conditions: lunch, and if your tank is too small to prevent encroachment on what a fish's biology informs his small brain is 'his' space, or his food supply.

In the ocean, one fish eats another,...

Ghosty problems in your tank? Consider your nitrate level.

Posted 07/24/2015 at 03:20 PM by Sk8r

Recommended or a reef---level of 2 or less.
For a FOWLR tank or fish-only: less than 30.
For many inverts, the survival limit: under 40.
Fish survival limit---maybe 100, but it's not going to be happy.

Some things actually use up nitrate: clams, for instance, reduce nitrate, but have many other high-end life requirements, so don't dump some poor clam into a fish-only.
Some corals like elegance also appear to require a little, so zero is not good for them....

A corals-first marine tank

Posted 07/11/2015 at 02:22 PM by Sk8r

A corals-first marine tank...
I've discussed this a couple of places, and some people are doing it, but let me put forward the advantages and the problems---if you have done or are contemplating doing it, chime in. It's at least worth a consideration, counting how prevalent parasites seem to have gotten in the hobby...

Pros
You can start setting up right after cycle.
You put your cuc in, dip, (do a short observation after dip for zoas, particularly) put a number...

How secure do you WANT your rockwork?

Posted 07/04/2015 at 01:52 PM by Sk8r

How secure do you WANT your rockwork?
My answer is 'not secure'. I balance, prop, lay it a bit like decorative brickwork, but what the ancients called 'drystane' or dry-stone, despite it being underwater. This means I rely on natural balance, I make my arches out of post-and-lintel and rely on gravity, and I do everything I can that way.

Why? Why not make it one rigid form that nothing can ever shake?

Because I have had to go in and do a fish-extraction that...
