I keep a fan on my tank so I go without a lid in a rimless tank and I’m wondering if two of my fish like… jumped out. I started with 5 endlers livebearers to start with then noticed 4. No dead fish, not even on the counter or behind the stand and or anywhere. Now this morning I wake up and there are only 3! No spike in ammonia, nitrites, phosphate, etc.

  1. I’ve been gold they do like to jump, and since they’re so small, they can dry up and stick to things when they do

    That can’t be all in the tank yea? I swear I saw a red cherry shrimp in the corner of the video, which combined with snails in my tanks cause every corpse guppy size or smaller to disappear in a single night lol

    It’s very possible your goobers simply didn’t make it and their bodies were cleaned up.

  3. You’d be surprised how fast a carcass can be stripped of flesh in a fish tank. Fish would eat eachother alive if they weren’t constantly swimming around

  4. These posts appear almost daily and every time its the same. Open lid, open windows. ”but i dont have a cat”

  5. Stuck in the corner, slowly decay and consumed. Check and maker sure there is no narrow space like behind filter slit, tight corner, dense plant area

  6. Could also be a dragonfly nymph hiding in there somewhere if it was introduced with your plants on accident

  7. Can’t tell from the clip, any chance they’re getting sacked into a filter? Maybe try some sort of temporary screen lid while you observe behavior and numbers.

    If you added any new plants watch for nymphs. I recently got some floaters and a starter colony for my newly cycled shrimp tank. Started with eight Im now down to three. I THINK I finally evicted all the damselflies though two made it to adulthood and were then evicted from my house

  9. fish do tend to eat each other when they pass. as another commenter stated, its also possible you have a damselfly or dragonfly nymph hiding somewhere in your tank and picking your fish off. they can be hard to spot. i would do a very thorough search to eliminate that possibility, as one nymph is easily capable of cleaning out your entire population of endlers.

    also, check your filter. fish get sucked into HOBs all the time. under decorations and things as well. with this number of plants and so few fish you may never notice a parameter change if one or two are decaying somewhere.
