a light might be nice but its not expected for the fish to stay alive.
I have kept fancy gold fish that are around 2x-3x bigger then the beta fish in a 10 gallon tank. There are stories of fish being ripped apart. If you watch the tank after adding a beta you should be able to find out quickly. The less crowed the tank the better. Betas are very territorial of space.
No, you cannot put these two fish together. In general you should keep Beta's alone by themselves, not even with other Beta's. They are mostly kept in bowls without a light, a heater or an oxygen line. The Beta will kill your guppy.
your tank was probably not covered. beta fish are very good jumpers.
I'm not sure you could say they 'like' light. They certainly need light in order to behave normally, eat, reproduce, etc.
The energy for the plants in a fish tank is supplied by Light.
if theres are other fish in the tank with him then his tail is getting eatin by the other fish and u need to get him out now. or he might just have fin rot.
The best type of light bulb for a fish tank is an LED light bulb. LED lights are energy-efficient, long-lasting, and provide the right spectrum of light for fish and plants in the tank.
This depends on the personality of your fish. Although, your fish may get stressed out if they are in total darkness all of the time. For a fact: bettas hate direct sunlight!! Never put your betta in direct sunlight, even for a short period of time. If you must, put them in the shade.
Yes, fish generally like having light in their tank as it helps them regulate their day and night cycles, and can also enhance their colors and overall well-being. However, it's important to provide a balance of light and darkness to mimic their natural environment.
A fish tank needs a light to provide illumination for the fish and plants inside. Light helps fish see, regulates their biological functions, and promotes the growth of plants through photosynthesis.
They can not go with there own kind but do well with guppies and larger fish...
