Just wanted to share these can do great in certain community tanks. I have mine in a 450 liter tank with Pearl Gouramis, 3 spot Gouramis, dwarf gouramis, betta splendens, white skirt tetras, cories, rubber plecos, and guppies. They are fine except for occasionally catching a slow male guppy (I just have the guppies in there for fry-food for them anyway). However, as some people have had them with hatchets, I would NOT recommend it. Mine, though unable to fit my former hatchetfish in their mouths, would bite them trying, which injured them enough that they later died. Smaller hatchetfish they did eat whole.
I love these fish! I have always had them in community tanks. It's fascinating to watch them snap up floating flakes. I feed mine flakes, crickets, and sometimes they pick off the feeder fish I give to my larger fish when they come to the surface. However, I have had four, and two of them have died suddenly overnight, when they were totally fine before...so I'd consider it a sensitive fish. They may be snippy towards other surface dwellers if they aren't given a generous amount of floating plants to hide in.
I have had 3 ABF for about a year now. I have moon lights in their tank and mine seem a lot more active at night. They just swim round and round the moon lights, waiting for a bug to land in the water and then it doesn't have a chance. Mine are active in the day too, but mostly at night. I recommend them for anyone who likes exotic fish.
This is one of my favorite fish in my tank. I have two of these that spend all of their time on the top of my 176 L community tank. They get a good helping every day or so of large wingless fruit flies, but they also consume a fair amount of flake food. They try to eat everything that comes their way in my case (including my finger sometimes). I don't know what sex they are, but I'm hoping that they are male and female. I want to see what their breeding habits are like.
I had an ABF quite a while ago now, but had him for around three years. He even lived through many escapes over the top of the tank. Every little opening was soon discovered. I spent hours watching him, mainly at night when I found him most active. Foodwise, he loved live house flies. So, I used to take a pair of tweezers, remove one wing so no flight by the fly was possible, and then drop into the tank a very upset and very active fly which Buddy could stalk. I miss him terribly, and can't wait to obtain another.
