dont know what to do with 20g tank

have 20g make it saltwater freshwater what should i put in it :?:

 

I have a 20G freshwater with a few Platy's, Neon Tetras, Corys and Otos.

 

stick with Freshwater unless you wouldnt mind paying hundreds of dollars on lights for saltwater...

 

Whatever you do, don't get mollies. I had a 20 gallon tank with six and in less than half a year I had a tank with close to thirty of them. I couldn't get rid of them because no one would take them or they already had too many themselves.

 

Saltwater 20gals are a challenge, but not too expensive. The lights aren't 100's of dollars, unless you want corals, but a simple live rock setup would do, with a goby, or a damsel, or a royal gramma.

 

actually for the live rock you would need a better filtration/water movement system which would cost you a little bit of money. If you dont add water movement such as a power head to a live rock tank dust and debris will build up on the rock and algae will become a problem. -tl

 

I haven't had any problems with my 20 gallon live rock collecting dust and debris. I do have good circulation in a tank, which isn't hard in a tank that small, with a whisper filter and a powerhead (powerheads aren't that expensive, $30 dollars maybe, and there is nothing wrong with getting used equipment as long as it works!). Also live rock IS a filter, any saltwater aquarist knows that. AND algae is NOT a bad thing, especially if it isn't brown algae, or hair algae (which are problematic), algae absorbs nitrates and phosphorus, which saltwater fish do not have a high tolerance for. So... 20 gallon saltwater is not out of the question. Saltwater is well worth the extra money, as long as you are smart and add slowly, research everything before you buy, and have lots of patients. The two things that are disadvantages with a 20 gallon: Limited in stocking the tank. Not much can be put in it without increasing the bioload. And the tank is unstable at certain times which can be moderated by water changes. So if you really want a saltwater 20 gallon and have experiance with freshwater, its only a step up.

 

i was talking about haired algae and brown algae jsut to inform you and it wouldnt be a problem as long as your circulation was good. -tl
