I have a 37 gallon with a valentini puffer clownfish and goby and am adding a yellowtail blenny and cherub angel from quarantine.
What one fish would you add if it was your tank?
 
5 fish is all I would put in a 37 gallon, especially one being a dwarf angel because they have a higher bioload. The cherub angel can also be pretty aggressive.
 
If you want a peaceful tank dont add the angel very aggressive my flame chase my mystery wrasse ,the 5th f I sh i would add is a blue dot jawfish very cool to watch

Don't add a jawfish, especially not a blue spot. Jawfish need at minimum a 5" sandbed to burrow, and blue spots are temperate species that will only live comfortably at the 66-70 degree mark.
 
If it were my tank I wouldn't add anything else. That angel in that size tank will probably harass any fish you add after him. The new fish will not have a good time.
 
I would add a Cherub, Flameback or Fireball angel, and add him last. Angels are so beautiful. These small angels should do fine in about 40 gal tank, even if they recommended for 55+ gal tank. My fireball never got even to 2 inches after 5 years. I had them in my 40 gal breeder and also in my 450 gal DT in the past. In the 450 gal DT, the Fireball spawned with my Cherub angel.

I generally agree that a BSJ isn't an ideal fish for a tropical reef. They will likely do better in a tank that is closer to their natural habitat.

But you are dead wrong about them being a temperate species. BSJ are a sub-tropical species that can handle temperatures up to 30°C for some time (for 5 months the temperatures near La Paz are above 27°C) during summer and fall. What they may need are seasonal temperature changes, especially if you plan on have them spawn. The temperature range they experience in their natural range goes from 16°C to 30°C (61°F - 86°F)
I compiled some information on this when researching the ideal conditions for my Blue Spot Jawfish. http://www.reefcentral.com/forums/showthread.php?t=2570213&page=2

Also, Jawfish can make due with far less than 5 inches of sand.

I second this. The bioload produced by the Cherub is huge. They are constantly eating on the rocks and sand and poop stings up to 4" or more LOL It produces as much bio load as 3 other fish of similar size do.

The aggression I get out of my Cherub is surprising. He's finally getting along for the most part but still has his "terrorist" moments :hammer:
 
Is that too much bioload for the tank with the five fish I already have? I have the Reef Octopus 1000 and am adding a canister filter.
 
+1 my only (at this time) and favorite fish!

this would be my choice! they are very peaceful with great personalities. up until a few days ago, i had a pair. removed half of my screen top to pull a dying clam and in the 5 seconds it took me to throw it outside, one of my hawkfish went carpet surfing. it was dark so i didn't notice it till the next morning. just make sure your tank is covered!!!

You already have them. So just see how it goes. Every tank is different. Only you can truly surmise if the bioload is too much or not.
 
I ran a 25 gallon cube with 9 fish at for over a year. One of which was Potters angel and the other a Dwarf Golden Moray (talk about bioload!). I did so knowing I was moving into a larger tank, but it was an SPS dominant tank that I couldn't even register nutrients in despite 3-4 feelings and aminos a day.

In my experience it's more about the aggression than bioload. Everyone's setups are different. My small tank was well prepared to handle very heavy bioloads (large skimmer, carbon sources, biomedia, etc). As long as your parameters are maintainable then I add fish until I notice aggression issues. Whether that's 2 or 10. But that's just what's worked for me.

For that size tank I'd look at chalk basslets. Very cool little fish.

I've got 8 in my 42. Water parameters doing fine. Corals and fish happy.

Good skimming. 25% water changes every two weeks. Running activated carbon and Phosguard.
 
Will the hawkfish get along with my blenny and goby? And would it be terrorized by my angel since it will be added last?
