I am very near to giving up on this tank of mine and am absolutely begging for help on this as I really do not want to get rid of the tank. I enjoy the tank but it seems like my fish are ALWAYS sick. Most recently I had a Bosemani develop a greyish dusty look to it and it died the next day. One of my Bosemanis ate a shrimp in my tank, so I figured it was that one and that was why it died. Now my other Bosemanis have this greyish dusty look to it and scratch once here and there. My other fish don't show this dusty look but some of them scratch, others don't. I just killed Ich in my tank about a month ago. Once I noticed the dusty look on the still living Bosemanis, I put copper safe and they have continued to live. I have live plants in my tank that have not been healthy due to poor lighting, but new lights are on the way to fix that problem. Is there any way the poor health of the plants can attribute to sickness? Can the eating of the shrimp have killed the one? Temperatures fluctuate between 78 and 82 in the tank. Could that constant fluctuation be stressing them out? How about lack of places for them to hide? Could that stress them out? I haven't picked up a lot of plants because of the lighting I have, but will be picking up more soon. I have a Fluvall or Rena canister filter which is rated for my size tank, so I do not believe filtration is my problem. Substrate is Seachem Fluorite, so I should be good there. I did notice some stringy white worm looking things when I vacuumed my gravel. They are not free floating or sticking to the sides of the tank. I think I said about all I could about factors that I believe may be contributing. Any and all help is very much appreciated. If there is something else that may be contributing to my constant misfortune that I may have left out, ask me about it... I really want to continue my hobby but near then end of my rope, my wifes rope, and the bottom of my wallet. Thanks
