Open to anybody who's kept fish indoors and may have a thought as to what the heck is going on in one of my tropical tanks ….
Ok so one tank I have is a fish tank everything else I have is for tropical shrimp!
The tropical tank for fish is a moderately dense live planted tank, soft sand at the bottom due to the species kept
Its a sealed tank ie has a fitted lid with a small flap that you slide back to feed the fish from.
There is a separate boxed fish proof filter system.
In the tank usual residents are very calm and sociable none aggressive fish....
Three dwarf chain loach fully grown each about as big as a neon tetra proper dwarf ones.
There are 6 neon tetra classed as a beginner fish as very hardy robust fish.
There WERE 5 glowlight tetra which is also classed as a beginner fish very hardy robust fish. Now there are only three.
All three species are the same size class nobody larger nobody aggressive classification.
I check my fish every morning and every night … kind of OCD like behaviour its getting to be make sure everybody is ok nothing untoward no signs of sickness etc. During the daytime I often watch them.....
So glowlight number one vanishes during the night next morning only 4 there … I search the tank … no sign of it …. at all in any shape or form. Thought flipping heck must have come down sick and the snails have done the clean up thing and zero evidence but they ain't exactly something you could polish off in such a short space of time… but did think it was a tad odd …. usually you see something or have a hint of something like the snails gathering in a particular area.... a fish away from the others and not behaving as per normal....
Stripped the tank did a head count and defo gone
So since fishy number one vanished have been feverishly head counting every time I look at the tank. Watching the others like a hawk in case there is a bully in the tank and that was the route cause. Count fish every morning and every night ….
Last night 3 dwarf chains, 6 neon tetra, four glowlight tetra …. this morning 3 dwarf chain, 6 neon tatra and 3 glowlights


Take out filter check it nothing, go through all the plants nothing ,,, take plants out and double check head count … nope missing and still not a sign of anything such as a body or a part of a body. There's no way to jump out the tank. This is only happening at night time... its only the glowlights ….. and the dwarf chains are too flipping little to do anything as they are smaller than the glowlights plus are bottom dwelling secretive dudes if I ever see them its because I have gone looking for them although they do love it when I do the weekly water change and will have a good turf around in the sand looking for things behaviour is unlike the middle swimming glows and neons which are always in view busying around etc.
So unless the fish fairy is paying a visit each night and stealing a glowlight there's something totally not right going on. The other glows just like the missing ones all seem healthy, active staying together with the other tetra and not bullying nor being bullied, not a mark on them, no listlessness, nobody looks sick in any way shape or form …..
The snails in the tank are ramshorns 4 large ones that the dwarf chains don't bother with as guess they are way too big - the chains do eat the snail eggs and the newly hatched snails though that are really dinky. I just can't figure out the vanishing glowlights ….. any ideas peeps?
