I recently moved my 5 loaches to a bigger aquarium. from 50g to a 150g.

in the 50g thy were not shy at all! playing and swimming out in the open. when i moved them to the 150g, they turned shy!! only come out when the lights are off. i have subdued lighting in the 150g. why would that be? anything i can do to get them to warm up in the new tank?

In the 50g they were with community fish. Swordies, tertras and mollies.
In the 150g they are with a 9" pleco, 2 x 3" angels and 2 x 2.5" IDs.
