i have this guy for about 6 month ,,,and he just start doing that now,,,so is that bad?? should i do some water change now? very smokey looking water now,,is there anyway to stop him or he will stop oneday?? thanks
yes, you need to do water changes now. i would have thought he'd have stopped by now but with the water so fouled he may spawning over and over.
a spawning incident in our tanks is brought on by stress and is a survival instinct, there may be something wrong with your water params. for now just try to clean the water by skimming and running lots of carbon as well as the water changes.
