Hi! I cleaned my tank and replaced the 2-4 cm black pebble substrate to 2-3 mm light-brown gravel. Ever since I put my bristlenoses back to the tank, they act in a strange way: they keep coming up for air and their fin movements seem nervous. It cannot be lack of oxigen because most of the water is fresh and the air pump is working. What is their problem? Are they in a shock? Please, help! Sponsored links

This could be related to temperature, water chemistry or even bulbs may be emitting too much light towards new substrate which definitely reflexes more light than black pebbles. Hard to tell without knowing more, even pictures haven't been attached. the developer of http://www.aqua-fish.net Yes, I am very busy. So accept my apologies since I cannot visit this forum too much. But I'll do my best because I own this website .
