I made a mistake of cycling with Tigers, and lost all six.![]()
Having kept Tigers for near on a year now I have noticed that if they have been overfed they become very lethargic and do headstands. I have also read somewhere (I`ll find it soon) that if the NitrItes start to rise they will also show the same behavour.
Sounds like your NitrItes are high or you could be overfeeding!!!
Found It.
