It's sick and/or dying.
It cold be time to get a new fish. I'm sorry for your loss
Question is not clear. Do you mean: "What types of tetra fish are there?" Neon, black neon, black, headlight-taillight, bleeding heart, carninal, glow-lite, to name a few, and there are many others.
Neon Tetras are shoaling fish and it will be absolutely terrified if it is alone. They should always be kept in groups of no less than 4 fish.
The fish maybe have a pregnant.
Tetra is Greek for the word four. Four in Spanish is cuatro.
AnswerNot necessarily. Fish tend to do this when you have just changed their cage or if they are resting. A fish is certainly dead though when it floats to the top! If the fish lays at the bottom, it could mean a few things. It could be sleeping, hiding, or it could be injured/dying. You should worry if it is laying on its side or breathing strangely. If it seems healthy, the fish could just have a problem with its swim bladder, the organ that helps them go up and down in the tank. If it is a catfish and is missing a barbel, that can also mess up their swimming.
four or 4
Tetra means four so in a compound such as carbon tetrachloride there are four chlorine atoms
i have a plec but i know someone who had loaches golden barb and a sharkfish and they were fine You can keep other fish of a similar size and temperament with tetras. You may also keep smaller sized Veil Angels with them, although your best bet is to stay with fish that are also brackish in nature. The size of your tank is also very important with determining appropriate tank mates.
it is the green neon tetra. its average adult length is around 2.5 cms which is about 0.98 inches. they swim in schools and is beautiful to look at with some lighting just because it is small doesn't mean it is hard to take care of but it is also not very easy
the prefix means four
Some fish prefer swimming at the top of the tank while others the bottom or middle.
