For the first time being in this hobby, I didn't research a species before purchasing it. I've always thoroughly researched anything that goes into my tank, even danios for my freshwater tanks.
My 90 gallon is fully cycled, so I thought that I would go purchase some fish. I purchased a yellow tailed damsel and a firefish; but on impulse, I also purchased a scooter blenny. The guy at the pet store said that the scooter blenny was an easy fish that will eat almost anything. He listed flake food, frozen food as well as live brine shrimp. As soon as I acclimated my fish, I decided to do some actual research on the scooter. I came to find out that they aren't even in the blenny family and their eating habits are "picky" to say the least. My tank is very young, so I didn't have an acceptable copepod culture when I bought him.
Within a week, his stomach got really skinny and he became less active. In a panic, I went to another pet store that sold live trigger pods
. I also bought some Garf Grunge because I've read that it contains a high number of copepods and ampipods.
Now, he's a lot more active and I can see that he's picking at the rocks constantly. My only concern is that his stomach is still very skinny. If I feed my other fish mysis shrimp, he'll take some, but he'll spit it out several times. I'm hoping that I have a large enough copepod count to sustain her. I'll shine a flash light into the tank about an hour after I turn off the lights and I'll see literally about a thousand pods
swimming in the water column. I'm just wondering if he's eating enough and if his stomach is going to fill out.
On a side note, the firefish and damsel are doing quite well. In fact, I'm somewhat surprised that the damsel seems kind of friendly.
