Yep me too ive lost 4 neon tetras this week, did see one of my congo tetras munching on one, dont know where the others have gone probably the same way.
Yes, that has happened to me. Kinda eerie, no fish and no corpse. I always check the filter to see if it's in there but it usually isn't. Then I check around the tank to see if it jumped out and it didn't. So it probably means my other fish ate it.
Yup....a neon tetra a few days ago...I took all ornaments out of the tank...checked in filters...NOTHING....but one of my platies was looking a little "large"
Whats worse is when you find a dead dried up fish that you never knew was missing in the first place...it had been "out of the tank" for quite sometime and I never even missed it...
two times as a matter of fact!!!
i lost a swordtail while i was on vacation and my brother swears it didn't die..and then i lost this tiger barb once...found him literally months later underneath the tank stand alll dried up and stuff..ew X)
My brother had eels, and one disappeared, here we found out it had gone up into the filter where the good water comes out and had jumped from there. We found a green dried up shriveled stick a week later under the living room chair.
I have had neons disappear too I have had others disappear but nomally find some trace of remains when I follow up with a suction through the substrate
But I have a fairly small tank (about 30 gallons uk) and I can sit for 1/2 an hour doing a fish count and be down by a few which are then there next time
It is not densely planted at all, no reason I can think off that would cause me to 'lose' two or three fish, of different types at a time which then come back later!
I do know that when i try to catch my barbs the last one or two can bury themselves head first in the substrate to hide for capture but these are rarely the ones missing
Wow, guess i am not alone. I just found it weird. One guppy and one swordtail missing and no corpse. How hungry can those fish get? i mean it was only one day. Scary
