There's really no way to stop them from moving. Reason they move is to get comfortable with the lighting/flow. Alternative is to put it in a floating basket, or get those species which doesn't move around.
Realized most crabs always hide from sight. The only crabs that doesn't hide are the Sri Lankan crabs that goes into our stomach! Chilli or black pepper style ...Haha..
10 years ago I had a 3ft mixed reef tank with chiller and gave up abt 3 yrs later due to work commitments. I started again recently and told myself to try my best NOT to use a chiller. Got myself a fan and able to keep the temperature bet 28-29. All LPS are fine BUT..... the water evaporation is killing me! At least on average 3 to 4 litres EVERYDAY!
And guess what..... Mr Chiller is back! And u knw that the corals are happier
Moral of the story.... Chiller is still the way to go especially with corals regardless LPS or SPS.
Used to use tube to feed. But for me, water still drip on the floor n wife will nagnagnag.... So now don't care just use syringe and put my hand in the tank since I always get the same end result........ nagnagnag from wife
