What Can I add to my 20 gallon

[cinsano11]

All my tests are at zero, Except Nitrates are at 20(Do nitrates go to 0 if so how).
I have an undergravel filter with powerhead, a penguin dual bio wheel 350, I use 4 filter pads,
and a fluercent 25w light used for corals.
I have a bar goby(3.5in), a clarki clown(2in), a lunare wrasse(3in), a brittle star, and a serpent star.
I was thinking of a pencil urchin, or some types of wrasse, tangs, or angels, not sure, something colorful.
Also what can I use as a vacation feeder for saltwater fish?

Your tank is at about fish capacity now. ABSOLUTELY no Tangs or Angels in there. The underground filter will haunt you later. All it does is trap crap under it. Your levels WILL go through the roof and kill everything IMHO.

I'm sorry, WELCOME to the boards. You can get all your questions answered here. Most PPL speak from experiance here. We are not out to sell you anything like the LFS(local fish store). How much LR and LS (live rock and live sand) do you have in the tank? How long has it been up?

If I were you I would take that wrasse back to the lfs and get rid of that under gravel filter. That wrasse wont last in that 20 gal for long ,that fish needs at least a 75g tank. keep doing water changes and your nitrates will go down. Also your options are pretty limited for keeping corals under a 25w light.

so tell me...what kind of corals do you plan on keeping in your 20 with 25w flourncent lighting? The warass will outgrow your tank very quickly, aim for some smaller fish.

I dont plan on keeping any corals, as far as militant ideas, return this, get rid of that well. Thats the kind of stuff fish stores tell you. Many would tell me all fish would die in a 20 gallon, but, to be honest, I have this tank running for 2 months no problems. I have no live rock. I really wanted ideas for hardy fish. Im sure if I put 1 more in it would be fine. One thing I find silly is this death proclomation by so many fish stores, and enthusiats. I have many setups, some fresh water, where everything should have died a long time ago. The fish look happy and play with each other and gravel. If I wanted to hear Im at capacity, and need to by a 75 gallon, with 3000 worth of stuff, id just go to certain pet stores. Some in my area have helped me with this set up, despite its interesting design. Come on give me some helpful help, its the Nano Section, anything is possible

i would definatly get some LR because LR is the best filtration you can have.

saltwater is not freshwater a general rule of thumb for saltwater fish is 1 inch of fish per 5 gallons of water this is just a general rule and can be bent but not broken. the wrasse may last a while but wrasse are very active fish and the lunar wrasse gets to be up to 10 inches. also it will become territorial and harass any new additions. but dont take my word for it do a google search on "lunare wrasse care" and compare some of what you read.
Dont take it the wrong way, most of the people on theese boards are here to help others and share ideas. I know I coulden't care less what size tank you have or how much you have spent I am just trying to help
