Thanks for the info. I keep the tank at about 78 degrees. I have 4 powerheads in the tank and when I calculated the gallons/hr circulation it was just over 10X my tank size, so I thought it was pretty decent. Maybe I'll try another brand of O2 test kit.

The Oxygen level in my 72 gallon reef tank is always low. I'm using the Salifert O2 Profi-Test and it barely registers on the scale at 2 mg/l. All other water parameters seem fine. I have tried increasing circulation, pointing a powerhead toward the water surface to create ripples, etc., but...

I want to remove the lid because there is only about 1 inch of space between the surface of the water and the glass lid. My Oxygen levels are very low and I think part of the problem is that there is not enough room for gas exchange. I think the 1 inch space above the water is probably filled...

I have a long nose hawkfish in a reef tank. I would like to remove the canopy permanently (for various reasons). Will he jump out of the tank?

A couple of questions: 1) How long has your tank been set up? 2) What are you using for circulation? 3) Describe the equipment and process you are using for water changes.

Pattie, Can you telk me exactly what these bumps look like? I've got a blue powder that recently developed a problem that sounds very similar.

I have a gorgeous powder blue that has recently got something that resembles a mosquito bite on his head. 3 days ago I noticed a single small white spot on his head. The next day it was gone and I figured everything is okay (maybe one of my cleaners got it). For the past few days he has had a...

I too have a powder blue that had the same thing when we first got him. Fortunately, he made friends with our 2 cleaner shrimp and we didn't have to do anything about it. Do you have any cleaners? They are not a "cure all" but they sure do help and problem has not resurfaced since! If the...

We have a really simple method for water changes that works great. Hardware used is as follows: -Large rubbermaid container (30 gallon trash bin) -1 heater -1 powerhead -10 feet of tubing We simply fill the container to the designated spot, add salt and chlorine remover, put the powerhead in...

I currently have 2 cleaner shrimp and 2 boxer shrimp in my 72 gallon tank. I would like to add a long nose hawkfish, but I have heard that the long nose might make dinner out of the shrimp. The shrimp and the long nose hawkfish would be about the same size. I would be interested in hearing from...

I have had this problem with goldfish in the past. I was feeding them flaked/pellet food that floated on the surface of the water. When the fish came up to feast, it would swallow a lot of O2 when it tried to eat the food. This would cause the fish to swim upside down (belly up) for a long time...

I have two coral banded shrimp (one yellow and one blue/purple). They leave my cleaners alone, and everything else including each other. They are reef safe (I have never have a problem). If you intend to get more than one, make sure they are either a mated pair or different species and have...

I've had a mandarin for a while and he changes colour to a pale grey/green every night. The first time I saw it I almost had a heart attack and thought he was dead. I now realize that it's normal behavior for a mandarin. Im not sure why they do this, but it does appear that when they "sleep"...

Ratbatty, Thanks for the link! It explained a lot about the behaviour of our shrimp lately and where they are in the cycle.

It's a cleaner shrimp. The male shrimp in the tank is very protective of her. Won't let her move more than an inch away from him!

Hmmm... seems to work fine from my computer. Is there a way to embed the photo in the body of a message?

My cleaner shrimp is "expecting"!!! :D Click on the link to see a hi-res photo! You can see the eggs quite clearly in her abdomen area. If anyone has had any experience with raising "little ones", I'd be interested in hearing from you. <a...

My flame hides all the time too. Every morning it's in a different place, but never where it can be seen. I don't feed mine either.

Anyone have a clue at all?
