My fish started to die. I had 14 small fish in a 20 gal tank for 3 or 4 years no problem then they started to die all at once. I took 5 remaining sick fish and put them in another tank and they got better. I did a water change and filter change then added 2 fish from the pet store watched them for 4 days and they got sick too. I put them in my other tank then they got better. So How do I clean this tank? Do I boil my gravel or get new? Do I use bleach on the glass? I have java ferns in this tank do I pitch them or rinse them and put them in another tank?
