I love it.... One of my favorite fish.
BummbleBee Gobies are predators. More specific, they are "ambush" predators.
What this means is that they usually sit in one place and wait for their prey to come swimming by.
Now, In the aquarium, this poses a problem. The problem is that when you feed your fish, you get fish swimming all over the place eating all the food that their is. the top water feeders are gulping air and food and the same time, the mid water feeders are right under them waiting for whatever they miss. The bottom feeders (unless you feed heavily) will somtimes comeuyp into the mid water colomn to get the food.
All the while, your poor little bummble bee gobie is sitting thier on his favorite leaf, rock or piece of wood "waiting" for his dinner to some right in front of him.
Now, to answer your question?????? I can't really. Mainely because I don't know what you have in the tank with him.
"ANY" schooling type of fish will QUICKLY devour all the food and leave your gobie (mine is named grumpy) with nothing to eat.
Here is what I did. And I now have "Grumpy" swimming up to the top of the water looking for food when I approach the tank.
~Side note...... 10g Planted. 15+ Male guppies, 1 Panda cory, 1 Clown loach, 1 Otto, 1 bummble bee gobbie (grumpy)~
First. I observed where his favorite place was. In other words, what his tereritory was. I then would feed my fish as I normally do. At the same time, I would place a couple of flakes (I was trying to get him to eat flake foods) in the water just about an inch or two above where he was sitting. After about three days, he started to take the flake that floated down in fron of him. Keep in mind, I '"DID NOT" feed him anything different than what I was feeding the rest of the tank. My thoughts were that he needs to learn the "smell" of the food.
I did this same thing for a couplew of weeks. Every other day, I would drop hi food a little further from him, making him come off hisd rock to get his dinner.
This went on for about a month, then low and behold, one night, I went to the tank to give them their nightly feeding, and guess what, o'le "Grumpy" swimms right up to the glass, to the top of the water, and EATS as I feed the other fish.
Now, everytime, I walk up to the tank, he swimms right up to the glass and acts like he's starving, just like the rest of the fish.
I feed flake twice a day and frozen blood worms once a day.
BTW. Bummble Bee Gobies are fin nippers. So be carefull about what you put in the tank with them. If you don't believe me, you should see the tails of my guppies.
