Flashlight Fish
I'm looking into getting 2 or 3 of these fish.
Has anyone kept them before? |

i have 3 now. theyre super easy. they eat anything, dont get bullied and arent bullies themselves.
they shouldnt be put in a reeftank though, metal hallides blind them. this blindness can be permanate too. the patches will seem white until they settle in. after about a month they will start to glow light blue. |

i wouldn't say only using T5's.........they are as bright as halides. For the same amount of wattage they are actually brigher when paired with individual reflectors.

You will not see them during the day. Joe Y keeps them in a reef tank and he says the moment the lights go out completely they come out. If you want to keep them in a reef, build them a cave out of PVC pipe or something that is deep enough to provide space and absolute darkness.
The fish above is an Anomalops sp. I wouldn't say they are "super easy". I wrote the following a while back to a friend: Quote:

I haven't been to Joe's reef at night but I do understand what you mean. We have several in a bare tank with no decoration approx 8' high by 8' wide that allows them quite a bit of room, and they do move fast. |

I have two in my 240 gallon, 8x2x2 and they use the whole tank at night. I have. A lot of live rock and very dark places for them to hang out in during the day. They are both eating like pigs. IMO this is the biggest challenge! I love to watch them swim around at night, they make it look like there are blue fireflies in the tank. I did buy 3 of them originally, but one never ate and died in a few days. Sparky and Big Guy are thriving so far, I have had them for a few weeks now.

Do you feed at night? Don't have the space or room now, but I've gotten increasingly interested in nocturnal fish that we can keep in our tanks.

Hey guys are your fish still thriving? Bought a pair. One doesn’t hide throughout the day while the other does hide. They did swim all through the tank last night but have not seen them eat as of yet. I’ll try tonight.

Have you been trying to feed them at night? When I prepare the frozen food for my daytime fish, I save some for the flashlight fish and feed them after lights out when they are out and about. Mine eat like hogs, even devouring pellets! If I’m awake early in the morning I will feed hem a little then too. One big problem I have had is that they both gradually lost the bioluminescent bacteria that grow in their glowing organs. After hours of research I found no remedy to this problem and wrote a few biologists who have studied bioluminescence. I finally got a reply yesterday with a good suggestion. The organs need a certain bacteria called bioluminescent vibrio that you can order online from science websites that you can put in the tank. He also said it won’t hurt the rest of the tank. I am going to try this and see what happens. Best of luck, I love my two! |

I have an update. I spoke to a marine biologist on the phone this morning who specifically studies this species and has done research on them for nearly two decades and she stated that the vibrio bacteria will NOT work with these fish as the bacteria that is present in their organs has never actually been identifiable. Weird. Anyway, her recommendation was that it is VITAL that they have a place to hide with COMPLETE darkness, that means not even any ambient light. We brainstormed and I decided to use 1 1/2 inch black pvc and use a few angles making kind of a curled around pipe that would be dark in the middle but allow water flow. I bought the materials today and will build them a new home tomorrow. She said that with complete darkness it takes a minimum of 6 months for them to regrow the bioluminescent bacteria that allows them to flash. Bummer it takes so long but I feel like I owe it to them. I will keep you posted.

Lmax8rn, any update on the revival of their symbiotic bioluminescent bacteria?

Flashlights light going out!!!
I see there are people with flashlight fish experience on this thread, and I need the help of those who are familiar with them first-hand! My flashlight fish’s lights have gone out!!!! They reflect light very well, which surprises me, but there is zero light when all the other light sources in the room are out I’ve read that it can happen, but not why, and what to do. He still seems as happy and healthy as before, just dark. He used to constantly flash all the time, but now he just leaves it open, I guess cause he’s wanting light. He’s still in my QT tank, where he’s been for 2-3 months now, and while I haven’t added any meds at all, the tank regularly has copper all the time, during the QT of regular fish, so there’s definitely some very low levels in the water, from the rocks and sand and silicone, and such, but I was never aware of copper specifically being anti-bacterial. He eats like a champ, and has since day 2, but all he eats is PE mysis, and I know even alone, that’s not a terrible diet, there may be nutrients and such that the bacteria need, that they’re not getting from just that. I’ve read with pinecone fish that extinguished lights can be “reignited”, but I don’t remember how, and now can’t find the source I read about it from, before. Can anyone help me? More-so, can anyone help my little guy shine again???
