New to salt water

20g is a little small for any tang to live in. you might want to consider any of these fish; however, the damsel fish might be a bit aggressive for most of these. Nano Fish

 

Nemos would be fine, tangs...egh, not so much

 

Just a quick update, the sand and live rock are turning brown (I know this is usual after a quick search on Google), API master test kit showing all readings are fine, water temp. is stable at 77.9F, the only problem is now the two damsels are fighting, any ideas?

 

Theyre going to do that until only one is left. I had 12 in a 75, I adequetly fed and had no problems.

 

1 clown sure but a tang is a no go for a 20G DT.:-/

 

I need some help!

Last night I did a water testing every reading looks fine, but the water start being cloudy, not micro bubble but like sugar powder...Do you know what's happening? Will my fish die?

 

What Moby **** said, I am also using that skimmer and you will find troubles right from the start, but it is effective after some modification, the problem is in the micro-bubble difuser, if you have issues with it, myself and others that use that skimmer can tell you how to fix it.

 

Maybe it is the picture but there appears to be ammonia no? Also from my experience with damsels they are little devils, my first salt tank experience I purchased one to cycle my biocube and he ended up killing my first clown. My biggest advice is take it slow, dont make big purchases or changes overnight. My only regret in the hobby was being too aggresive on the start up. Otherwise the tank looks great.

 

hehe I knew the tang police were gonna jump on you
But the tank looks great! Hopefully you're looking to add some softies!
Welcome to 3reef!

 

Sorry for jumping in, but I also have a Coralife 65G in one of my tanks. It has been running for 2-3 weeks now, but still bubbles. What did you do to the micro-bubble diffuser to stop them?
