Knight Goby

Yes, I know. I am a brackish fish lover with a fresh water tank. I really need to find another tank spot and put the other tank up that I have. I keep saying that and DIY projects at my house keep coming up. Problem is I LOVE having my tank in the same area as my chair is and I don't have another spot where I can Sit, and view my tank while I am watching TV or just in the room reading or on the computer. I need a bigger house; HAHAHA! Like that is going to help.
 
PS: I have had the Mac for about 3 to 4 months.
 
Mabel,

Are you testing the salinity with a hydrometer or refractometer? Water evaporates, salt doesn't. The other fish you have will be killed with salt. You have fish that require VERY different water conditions in the same tank. I hate to be a wet blanket, but I'd hate to see such a striking fish come to harm.

Sorry, I don't know what a hydrometer or a refractometer is. So, the answer is no, I am not testing the water. I go more by his actions and how active he is. Before I started reading about him I defiantly noticed that he wasn't as active as he is now, that I have been adding the Salt. The other fish look good.
 
A hydrometer (less accurate) or a refractometer (more accurate) allow you to test the salinity of the water. You'll need to know this to have a successful brackish tank... and you'll need to find new homes for the fish that are FW fish.

Again, are you using aquarium salt or marine salt? Marine salt is necessary for a brackish tank.
 
I am not sure. I got it in a plastic bag from my LFS. What is the difference between Marine and Aquarium?
 
Aquarium salt is salt.

Marine salt includes trace elements that are necessary to run a successful marine or brackish tank.

What does the bag say?
 
Nothing, it was a ziper sandwich bag. She took some out of a bigger bag that I don't know if it said anything. I bought the fish from my LFS that gave me the salt and she had the fish a while before I bought him. In reading the above link it sounds like my water will be okay and he is in similar water that he came from, so for now = I am good.
Do you have a suggestion of feeding him something other than Blood worms or Shrimp?

I give. Feed it guppies.
 
Mabel,

You really can't just assume that "you're good." You need to find out if you got Marine salt or just salt. Your Knight will die in the end, meaning it doesn't matter WHAT you feed him in the meantime.
