Hi, seven days ago i bought four fish; two Glass blood fin and two rummy nose. When they started living in their new home they seemed fine but the next day they we'rent eating any of the food i had been feeding them and my light blew, so it was a dark atmosphere for long periods of time. Three days ago one of the rummy nose died, and i also got and new light the day before. Now every time i turn the light on after having it off, i notice the glass blood fin are very pale and their red fin is almost completely pale as well with a slight amount of red. My fish still aren't eating and I've seen them "darting" around a little bit.
