I have bristlenose catfish shrimp neon tetras and mini mollies, and my light is broken I was looking at getting 2 bright led lights for the tank
The fish can live with no tank light at all. Lights are for 2 reasons. 1 - Grow live plants 2 - See your fish better Otherwise they can live just fine with the normal room lights. Ian
Room light is enough for your fish and shrimp unless you are growing live plants in their tank. LED lights would also be fine.
Yes, it should be possible. But not very nice for them. Remember that when their is no light energy, the plants cannot photosynthesis and therefore no oxygen. If the bowl remains with no oxygen for too long then the fish will die.
