CelesteAmie Posted December 11, 2014 Report Share Posted December 11, 2014 Hi I recently started adding fish to my tank 3ft 140L and I thought to keep the water at good levels I will slowly add everything and work it up. So I added 5 small tetras (neon) they seem happy and healthy. And usually swim as a group. But there is one tetra that is often found swimming by itself. Not sure why this is or if he is sick? I've been keeping a close eye on it. But just wondering I'd this is normal and if im just overreacting or not? Link to comment Share on other sites More sharing options...
phoenix230197 Posted December 12, 2014 Report Share Posted December 12, 2014 I had 15 neons in my 6x2x2.5, until my Heckelii ate them, and they (neons) would split up and occasionally 1 or more would go off on their own (different areas) for a few days and then they'd come back to the school. All my other schooling fish do the same too. Link to comment Share on other sites More sharing options...

It is quite common that in a school of Neons, 1 or 2 will go off and do their own thing. It can also be the sign of disease. So long as your fish are eating and are full colour - I wouldn't be too worried. If there were other fish in the tank that were a threat to them - chances are they'd "ball up" in a tight school. With no threats - it's not uncommon for them to go off on their own. Keep an eye on it - but so long as it is eating and is fully coloured and has no obvious signs of disease - don't worry.
