Here’s an alphabetical listing of the most common issues and diseases that can affect fish and their environments:

Fish infection with Gram-positive bacteria. Both bacterial species cause serious health disorders in different species of freshwater and marine fish: rainbow trout and other salmonids from the Oncorhynchus family, eels, and fish belonging to the Ictaluridae (catfish) and Cichlidae (tilapia) families (3).

People, especially those with open skin abrasions or scrapes, could get infected by Streptococcus iniae bacteria while handling fish or cleaning aquariums. Affected people usually develop a skin infection at the site of open cuts or scrapes.

• Ammonia poisoning. High levels of ammonia can buildup in your fish tank.
• Columnaris.
• Fin Rot.
• Ich.
• Nitrite poisoning.
• Velvet.

​Bleach Solution.

1. ​Put the bleach in a spray bottle and spray the inside of the aquarium.
2. Use a 8:1 water/bleach ratio to fill the aquarium.
3. Once the tank has been left to dry for 24 hours, fill it with water and add a dechlorinator.
4. Empty the tank and refill adding the dechlorinator, and the tank is now ready to use.

The answer is yes; when used in proper concentrations, bleach is safe for aquarium use. If you follow the rules, bleach is safe to clean your aquarium, equipment and even plants. It will safely and effectively disinfect glass, equipment, and accessories in your fish tank.

​*Bleach is very dangerous to fish. Be sure to remove all fish from the area you are working in. ​*Bleach can cause skin irritation and is harmful if ingested or comes into contact with the eyes.

Lay the tank down on a towel, and pour enough vinegar on the affected glass to cover it. Let it sit for 10 to 20 minutes, then scrub with a non-abrasive pad or cloth. If you have a stubborn patch of build-up, try using a razor blade or algae scraper to gently scrape the scale away from only glass panels.

Equipment You Need to Clean a Fish Tank

• Bleach.
• Razorblade or, if you have an acrylic tank, a plastic blade.
• Algae pad or scraper.
• Filter media and brush.
• Bucket solely for use in aquariums.
• Glass cleaner or lime remover for aquariums.
• Paper towels.
• Chlorine remover.

Depending on how many fish you have, and how messy they are, most tanks require cleaning about once every two weeks. Cleaning should involve: ✔ Siphoning the gravel to remove any debris and uneaten food, and changing about 10-15% of the water.

It’s not advised to remove your fish when cleaning unless absolutely necessary; removal will stress them and can make them sick. If necessary, gently remove your fish with a net and place them in a large bucket with some of the original tank water.

Vacuum the Gravel Fish feces, shed scales, uneaten food, dead bits of plants, and other debris will settle to the bottom of your tank. Vacuuming the gravel every week will remove much of this debris and refresh the tank, brightening the gravel and keeping the tank healthier.

You should do a 25% water change every two to four weeks. There is no reason to remove the fish during the water change. Make sure you stir the gravel or use a gravel cleaner during the water change.

There really are no “bad” snails, but a few species can multiply unchecked and overrun an aquarium. Seeing hundreds, if not thousands of these little beasts taking over your tank can be unnerving, and they can place a burden on biological filtration as well as clog filter intake tubes.
