We add different accessories to improve the aesthetic of the tank. There are plenty of decorative items like colorful pebbles, rocks, crystals, coconut shells, and much more that you may choose from the fish store. However, sometimes one wrong choice may cost you your adorable fish. Sometimes adding a few foreign items could pose a real threat to the well-being of your fish and tank.
Therefore, today, we are with a list of some of the items that you should completely avoid putting in your fish tank. So check it out, make better decisions, and safeguard your fish.
Objects with sharp ends
Just like we avoid coming in contact with sharp objects, our fish too need protection from them. Many times some decorative items like rocks have sharp points that can harm fish. Therefore, whenever you buy any stone, pebble or crystal check it thoroughly by putting it in your hand for any sharpness. Make sure it doesn’t have any pointed ends and is smooth. While playing fish may get hurt with such objects, get bruises, and harm them.
Eatables other than fish food
Fish generally munch upon everything that you will put in your tank. Apart from feeding them fish food, giving some of the fruits and vegetables is also fine. However, sometimes people put fried food, chips, bread, and related food which is a strict NO. Although fish will consume them, they will cause more harm than good. You should never put any random food to the tank until you know whether it is safe for the fish consumption or not.
Other than being harmful to the fish, such food also deteriorates the quality of water in the tank. For instance, chips contain salt and oil that mix with water and drop off its quality. It will change the water parameters entirely. Therefore, stick to regular fish food and do not feed everything that your other pet could eat.
Chemicals not only change the water parameters, but they can significantly affect aquatic life. People tend to think that the way chlorine used to clean the pool water; it will work likewise in the tank as well. Chemicals should be avoided as far as they are explicitly meant for the tank. When there are living creatures in the aquarium, any chemical could pose a danger to their life. Even a small amount can do significant damage.
Decorating the tank using rocks is not new. You can find plenty of colorful and beautiful rocks at fish stores. They are treated and are safe for the aquarium. On the other hand, the rocks from outside are dirty and have plenty of harmful microorganisms. No matter how properly you wash the rocks until they are not treated, they are not safe to add to the tank. Roadside rocks can alter water chemistry and even change the color of the water. They are not safe for the fish as well. So, always go for store rocks rather than any random rock collected from outside.
Wood certainly is one of the best decorative items for tanks but putting any wood is not a good idea. Woods need to be treated before introducing them to the tank. Tannin, one of the chemicals present in the wood could pose serious harm to the fish. Therefore, always go for the woods that are sold in the fish store. They are well-treated. If you find a nice wooden decorative item outside, wash and boil it properly to remove the impurities. However, this is not the best way to make it aquarium-ready. Once you add wood, change the water regularly as it may alter the color and chemistry of water.
Fish from river or ponds
You might catch a beautiful fish in the river or pond and want to add it to your tank. Beware; it’s a terrible idea. There are two good reasons to avoid adding fish to the tank. First of all, they might carry diseases from their wild homes to your tank and infect your fish as well. Secondly, this practice is not safe for them, as well. Fish need time to acclimatize to the new environment. Adding directly from the wild environment to the new one puts them to stress that may eventually lead to their death.
Snails or worms from outside
Just like fish, you should also avoid adding any wild snail or worm from outside. Easy to find anywhere, the temptation to add them directly to the tank rises. Such snails and worms might be the carrier of some harmful microorganisms that can pose a threat to the fish. Instead, go for the bloodworms and snails that are found in the fish store. They are safe for the fish and can mingle with them easily.
Some metals release toxins to the environment. Some might rust when coming in contact with water. Both toxins and rust are harmful to the aquarium. Therefore, try avoiding metals in the aquarium unless they are specially made for the tanks and are aquarium safe. Likewise, do not add coins to the water. Coins corrode and release harmful toxins to the water, changing its chemistry altogether.
