I am setting up 75 gallon FO no live rock (tons of decorative coral)
Filtration at my disposal- wet/dry filter, Magnum 350, Fluval 304, Protein skimmer, and a UV sterilizer. I want to do smaller size fish (damsels, gobys, Dottyback). Would 15 small fish be too much for this tank providing water quality is pristine, water changes done weekly and plenty of coral to mark off territory? My concern is not a biological overload, but moreso a psychological overload on the fish.
Please let me know your thoughts. thanks in advanced!!
 
If you go witha more peacefull comunity(perc or oceleris clowns, blue or blue green chromis, gobys, and any other fish you have done extensive research on and concluded to be peacefull) than yes, if you stick with what your planning on than you could end up with only one damsel in the long run.

Please do some reearch and give us a more acurate description of what fish you want to keep(narrowed down to species).
 
Stocking level is as follows: 4 green chromis, 2 yellow tail damsels, 1 royal dottyback, 2 cardinals, 2 clown gobys, 1 pygmy angel, 1 jawfish and maybe a watchman goby. Reasearch is being done on compatibility.

You will have problems with this mix I am sure. You would need a good sandbed for the watchman and jaw fish who require good depth substrate to burrow in. If you do that you would need the ckeanup crew necessary to maintain the sand bed and my recommendation would be live rock. So unless you are willing to go live rock and a dsb I think the jawfish/watchman gobies are out. The chromis do better in odd numbers....I am not sure why but between them, the damnsels oops I mean damsels and the angel you are looking at fish that are all territorial and can hassle any new additions to the point of death. Some will say the chromis are peaceful...yeah right I had the only 5 in existence then that were the biggest bullies I had ever seen and what a b****ch to catch them afterwards. Clown gobies are nice little peaceful fish and would be great additions to a peaceful community tank provided the pair you get are a mated pair. Just buying 2 is not a guarantee they will get along. Time to get out some books and check the compatability issues. Sorry to be such a downer on your plan but foresight will ensure that you have happy stressfree livestock.
 
i wont comment on the fish but with that many and without live rock and using a wet dry you are going to have a real bad time with nitrates and algae
 
about 30 is as high as it has gotten in my tank, wich is about the level you should start to worry IMO, wether it's fresh, brackish, or saltwater.
 
i recomend putting a few pounds of live rock in there. It will quicken the rate that your decorative corals become live rock. ( i am assuming you are talking about coral skeletons and not those plastic ones). It will also seed your tank with coraline, pods, bristle worms, and other benificial creatures that are commonly found in live rock.
 
Actually thats not a bad selection. I would just get rid of the damsels, clown gobies, watchman and the jawfish. Never introduce a blenny or a goby into a new tank. Wait at least a year. I would wait longer if it were me.

Green Chromis are relatively peaceful. I have never seen them "bully." They are awsome to watch when they school and actually help accilmate fish by swimming around them and encouraging them.

Just delete the fish I stated out of your stocking list and it should be fine. There is no reason to rush. This can be a very expensive hobby. Why rush and make it more?
