Re: how many salt fish and what is need for salt s
Hmmm, alright, a 55 gallon is a great size for the begginer saltwater aquarist. Big enough to hold a variety of fishes, small enough to fit in anyones budget. The basics you are going to need are
Live sand, I suggest a minimum of a 3" sand bed. A nice deep sandbed (no such thing as to deep) will be a main part of your filter system.
Live rock, is another important part. Your probably going to want atleast 1 pd per gallon, if not more. You don't want to much, so thats all you see, but, live rock is your main filtration.
Power heads, there more important if your doing a reef tank, but your saltwater fish need them to, you prolly want 3-4 strong power heads. I have one on my 3 gallon that does 68 gph and I still worry it isn't enough.
A skimmer, I don't use skimminers, my tanks are only 3-3.5 gallons, I don't need them. However, with a tank that size, you will. Bakpaks and skilters I've heard are good, however, I've personally never had experience with either, so, you might want to ask sumone else about that one.
Salt, Instant Ocean is a good, you prolly want the 150 gallon buckets. The 150 gallon refures to how much saltwater it will make.
Hydrometer, a must have. A hydrometer measures the amount of salt in your water, do not skimp, go for the good one.
As for your filter, basically all it'll be good for it water movement, and if you have any meds in the water that you need to get rid of.
Lighting, if you are doing a fish only system, the standard lighting will be fine. If you choose to upgrade to a reef some day, you'll want to upgrade to power compacts if not Medal Hailides.
Now, for the fun part, FISH. While a 55 gallon tank, may look big, in the saltwater world, it really isn't. Remember that these fish come from the worlds most stable enviroment, and, if they are wild caught, this will be a big shocker for em. Follow Coleseas and dattacks advice, and leave the tangs in the ocean, there just to fragile of creatures for a novice. For your tank, I suggest
1 False Percula Clownfish, a great beginners fish. I wouldn't add it as your first fish, but if you watch you water carefully, it should be ok.
Angels are good, but, require a little more care then a novice can give, so, I would hold off on those for a while, until you get the hang of it.
Blue, Yellow-tailed, Domino, 4-Striped, 3-Striped Damsels are all great first fish. There extremely hardy they eat anything, but, there also aggressive. Great for cycling your tank, but once your done with that, most bring them back to the LFS so they stop beating up there new fish.
Wrasses - 6 line and cleaner can come in very useful in a cycled tank, cleaning the parasites off of your other fish. Great to look into. Personally, I love the 6 stripe, very colorful, but, also very skittish.
Gobies - Another fine group of fishes, easy enough for the novice. There colorful little bottom feeders, that come in a variety of shapes and sizes. I'm partial to the green banded, the red headed, the clowns, and the neons. All are great fish, that stay under 3" and are extremely colorful.
Mandarins/Dragonettes/ and Blennys - Stay Away! A couple more groups of fish that should be left in the ocean. All of these fish eat the copeods that live in the live sand in your tank, exculisivly. A mature (4+ yrs) 55 gallon tank, might be able to substane one, but, probably not with out a refugium.
Shrimp are a vital part of your marine system. Cleaners and peppermint are great choices, with the added bonus that the peppermint will eat you aiptasia (pest) anenomes that may come in on the live rock. The cleaners, will clean the parasites off of your fish.
Snails are another improtant part of your tank. They eat the algae, what more needs to be said?
Hmm, think I've said as much as my lil fingers can handle. It's barely skimming the surface of just the basics you need to know on keeping a saltwater tank. Research is the most imortant factor. U have to know what needs to be done, for everything to work. If your missing one thing, the whole tank could crash. This is a big investment. Expect to spend atleast 50$ per gallon on just the equipment and live stock alone. If you choose to do a reef sumtime in the future, expect to triple that. Take your time, this is not something you want to rush into. KeEp posting, I love to hear how things are progressing!! HTH
