    Added bulkheads to my tank

    Wow... that turned out really good! Sorry about your fish, but at least you didn't trash the tank. I think that's supposed to be a "silver lining" kind of thing...

    Maybe this'll be better.

    I hope this file loads from my phone. If so, you can easily see the spines on this NT: content://media/external/file/9716

    New to the Hobby

    Ditto to all of the above. Think about what you want the tank to look like a few years from now. Once you make that decision, you'll have a good starting point. The equipment necessary should revolve around what you want in your tank. It's basically a choice of FOWLR or reef. FOWLR is pretty...

    Harlequin tusk help!

    Look for small horizontal "slits" in the orange spots on either side the white streak. They're called surgeonfish because they have these "scalpels".

    Harlequin tusk help!

    Folded down against each side. The two spines on each side of the cauldal peduncle are retractable. They're used for defense or aggression. The cauldal peduncle is the small spot just before the tail. Unlike the yellow tang, which has one barb on each side, the naso has two on each side. View...

    Could help. Good thing my yellow keeps his barbs retracted, or there would be bleeding fish all over my tank! He doesn't hesitate to bump another fish if he can get the morsel he's after...

    Back to basics- 29g adventure

    Woopie! Congratulations, Seth!!! Long week my a*@... it's going to be a long 18+ years!!! Sorry pal, I couldn't resist. There's nothing like raising a child, and I know you'll have lots to teach the little guy. Yeah... some pics would be nice. Maybe you can hold him by the fish tank? Just a...

    Circulation Pump

    Are the suction cups on the pump still flexible, or are they stiff? If still flexible, make sure there isn't anything on them to cause them to lose suction. A little coralline algae will prevent them from sticking. If you can't get them to stick, you may get lucky and find compatible suction...

    Sump: Will this work for a 20 gallon aquarium?

    You're welcome. That's a good question. It's hard to say, but I think it might be hard for a fish that only reaches 1 1/2" to swallow a 1/2" shrimp. It's possible that they may coexist, but there's no guarantee that the goby won't develop a taste for fresh shrimp meat. Can't remember how many...

    Harlequin tusk help!

    Since he's not seeing any aggression in tank, and it's a single wound, makes me think it was most likely an accidental injury. Nasos cant retract their spines like Yellows, so a simple feeding frenzy would be all it would take to end up with a gash. Of course... this is pure speculation. The...

    Sump: Will this work for a 20 gallon aquarium?

    Your should turn off either the HOB filter, or skimmer, or both when feeding so the food doesn't get blown away. I'm sure LT will find it eventually, but it may have started decaying by that time. This will add to the nasties in the water. Just a suggestion. Yeah, I could see how it would be a...

    It's possible it caught a spine on the naso if it swam too close. Just a thought...

    Well done! The cycle should be complete any day now. Getting exciting now, isn't it? LOL!!! :D

    Sump: Will this work for a 20 gallon aquarium?

    Sounds like it's almost done with cycling. Just need the nitrite to go to zero, and then do a large water change to get the nitrated down. Fish can live with a good bit of nitrate, but I think it's healthier for them if it's closer to zero. Perhaps when you get some macro algae in the fuge...

    What is it?

    Same here. I have a few in my tank. They aren't invasive like aiptasia or majano, so I leave them be. Majano looks like a deflated, brown-colored BTA... ;)

    Sump: Will this work for a 20 gallon aquarium?

    No. Since it's just a sump with fresh saltwater, it won't affect the tank. Just be sure the water temp and salinity are the same as the tank water before you start up the return pump. It wouldn't be a bad idea to take a gallon or two from the tank and put it in the sump, and replace the water in...

    Fine Dust

    It takes a balance of Alkalinity, Calcium, and Magnesium to keep this from happening. I hope you're testing your water to see what these levels are. Never add anything to your tank before testing to see if it even needs it, and always test afterwards to make sure you aren't under-dosing or...

    Why I continue to use Reef Crystals...

    You are absolutely correct on all of the above. This is very good advice, and I do all of the above. I mix my saltwater in my basement where the temp is never above 65F. 1. Saltwater mixes with less precipitation in cold water. The water in my mixing vat is usually about 60F. 2.I use a 2400...

    Fine Dust

    Could be most anything. A large fish digging a bed in the sand will cause this... but the first thing that came to mind was calcium carbonate. Is it a whitish, or light tannish looking substance? Does it appear more on you heater and power heads? This is usually a sign of low magnesium, or an...
