I have 5 zebra danios and 5 neon tetras in my 30 gallon tank. There is also a relatively large shell (it's a real seashell that spirals inwards). The opening faces towards the ground and rests on the gravel itself.
Yesterday i noticed one of my tetras missing. After looking around a while, i figured he was probably inside the shell hiding. I've noticed sometimes they go in there.
After a few hours, my tetra was still missing. So i picked up the shell. Nothing. I was worried he might be trapped or lost in the spirals of the shell, not able to see any light at the opening! So i rotated the shell such that the opening moved away from the water instead of scooping the water. After one rotation, my fish magically appeared.
Oddly he seemed fine. He didn't swim madly away. He just kinda hung out for a few seconds and then calmly rejoined his friends.
Today this morning, the same thing happened again. I recovered the fish just like before, and he didn't seem stressed at all. But i removed the shell anyway and replaced it with a thermos mug.
So...can fish really get lost in the shell spirals? I doubt he was physically stuck (even tho i've read about that before). Since he didn't appear stressed, it's possible he just wanted to hide/sleep...maybe even mate? I've never seen 2 fish in the shell at once, but who knows.
Any thoughts? Any similar experiences?
