I'm not sure if the one i had was just too powefull, It was the filter that came with the tank... its only 60litres, when i turned it on the current was too strong for my poor axies to stand on the floor! they were caught in a cyclone! I bought a replacement for £20 so it does not matter, Did you arrange the rocks yourself? or is it a ready made ornament?
Ha ha ha, Look at Mo Mo just chilling out on his plant! My guys always do that in the morning they just stare at me! I like the look of your tank, I had the same filter but my guys hated it!
Yip thats me same person, ive never had to use a fan for my tanks as living in scotland its always cold a bonus for my axolotls tho :)
Why do you think you need one does your temp go quite high in your tank?
I use the stick on one in one of my tanks, but i have the glass ones which is in most i find them quite accurate you can pick them up for around three quid i think :)
