Planted Aquarium Care


Just like planning for a regular aquarium, planted aquarium needs research and preparation. Planted aquariums are often times preferred by hobbyists for its cool greenery.

Choosing Plants

Remember that not all plants can be put in the aquarium, only aquatic plants. Some plants require more lights and more CO2, so if you want to save on the lights, choose plants that require less light. Some of the aquatic plants are Ceratopteris thalictroides (Water Sprite), Hygrophilla angustifolia (Willow Leaf Hygrophilla), Hygrophilla difformis (Water Wisteria), Hygrophilla polysperma (Small Leafed Hygrophilla), Vesicularia dubyana (Java Moss).



Some plants do well with the normal aquarium lights but some plants need more lights. So do research on the type of the plant you have to know the light requirement. Also, avoid tall aquariums as light cannot penetrate easily in the tall aquariums.

Substrate and Water

Some plants can do well with aquarium soil and clay while others need woods. Some substrates provides nutrients to the plants.

Most of the planted aquariums can do fine with the normal tap water however check your water’s quality and hardness. For most plants, the water should not be harder than KH 8, the phosphate levels should be under 0.5 mg/L and the nitrate levels should not exceed 10 mg/L.


Fish for Planted Aquarium

What is planted aquarium when there is no fish. Though you cannot keep most of the fish species in the planted aquariums, there are some schooling fish that are best for planted aquariums. Some of them are: Cardinal Tetras (P. axelrodi), Rummynose Tetras (H. rhodostomus), Green Neon (P. simulans), Red Phantom Tetra (M. sweglesi), Tube-mouthed Pencilfish (N. eques), and Silver Hatchetfish, Marbled Hatchetfish (G. sternicla and C. strigata).

Rainbow Shark Care


Rainbow Shark or Red fin shark, Ruby shark, Red Shark is known for its 2 pairs of sensitive barbells beside the mouth which are used to search for food. Rainbow shark has also different shade of body ranging from brown, blue, gray, or black with it’s famous red fins.

Rainbow Sharks feed on the leftover food that are mostly found in the bottom of the tank so with them, you are sure that your tank is  always clean.

 Rainbow Shark Care

Rainbow Sharks cannot eat pellets, they rely on the left over food by its tank mates. These food are usually powdered or crushed by other fish.

Rainbow Shark is aggressive towards another Rainbow Shark so keeping a couple is not really advisable. It is semi-aggressive to other fish but usually can be kept with most aquarium fishes.

The Rainbow shark needs at least 55 gallon tank size and with rocks, shades, plants. It needs hiding place.  The water temperature should be between 24 -27 degrees Celsius.

Rainbow Shark Breeding

Since Rainbow sharks are aggressive towards each other, breeding is difficult and with low result.

My rainbow shark has been to all the tanks. It has been the tank mate of molly, guppies, cichlids, parrot fish, and others. He always keeps my tank clean 🙂
