My 29 gal tank is fully cycled, 0 amonnia, 0 nitrites. My population includes 1 common pleco (5 in at last measure), 1 Chinese algae eater, 5 blue danios, 1 fiddler crab (he has access to dry gravel via an upside down flower pot with an air bubble in it), and several snail interlopers. Tank is planted with Amazon swords. SO... my pleco had ich about 2 weeks ago... I treated by raising temp to 84 degrees for several days... spots disappeared. I kept temp up, no spots for at least three more weeks. Now my danios (that I just added 2 weeks ago) have ich spots. I've been avoiding treatment with meds because I really don't want my pleco to get killed from it. But am I always going to have ich unless I treat with malachite green or copper? What if I do 100 percent water changes and also change out all my filters (keeping only my biowheel)? Will that be worth having to partially cycle again or will ich just reappear? If I DO treat with malachite green or copper, will it kill my filters and/or pleco? Thanks.
