Hey there guys,
I have a 55 gal. and i have 1 oscar and 3 jack dempseys. Heres the prolem i have, during the day i dont leave the light on to the aquarium, i leave a window curtain a little open, till i get home at 5. Then i turn it on and turn it off right before bed at 11 or so. but the other night the oscar ran into a rock in the middle of the night while the light was off and now is blind from 1 eye. Does anyone leave the light on over night or what should i do? Its happen more than once, i wake up and some fish will have scales missing, im thinking they have to run into things. But ive heard leaving the light on for to long causes alge to grow. Can some one help please?
