I have a few red eye tetras in a 20 gallon long aquarium and they are lively. They can be a bit aggressive at times with smaller fish, and don't even think about putting them in with any type of small invertebrates, such as ghost or cherry shrimp, since they will devour them. Other than that, red eyes are an entertaining fish that are reasonably hardy, and in groups large enough for them to school, can be quite striking to look at.

I've had 3 red-eyes for over 3 years now and one of them has a small bloat in front of the anal fin, does anyone know what this is?

    Hard to say for sure, but there are several possibilities. It could be constipation, possibly a pregnant female storing eggs, a swim bladder problem, or an internal parasite. Constipation would look like a swollen tummy - the area right behind the ventral fins and right in front of the anal fin. A pregnant female also has a swollen area infront of the anal fin, so that could be more likely if your fish still has a healthy appetite.

hi =) i have a sugar glider, they're an OK pet. They don't come out often and you have to take them out to exercise them, and sometimes it's hard. And they have specific diets. I am a licensed Veterinarian.

We had two of these in a tank with assorted guppies, and they killed one of the guppies and were nipping at the others before I removed them. What could cause this?

    Tetras can be a bit nippy at times.  May need to add more tetras so they will school and this will normally keep that behavior in the group.

I think these fish are only for begineers, good fish but chasing one another. White cloud mountain is better

    It depends on what kind of gouramis you have. Some might be fine with the tetras but some can be agressive toward smaller fish.

Lemon tetras and red eye tetras are great hardy tetras for beginners, they look some what alike.

These fish are the most beautiful fish in my tank. They stay in a school and no one tries to attack them they are peaceful with cherry barbs, moonlight gouramis, and red blue gouramis.

I have 2 of them, but their body does not resemble them at all. They have red eyes, but their shape and fins resemble a Black Phantom Tetra.

Just got 2 red eyed tetras on Wednesday. [Today is Monday] They are very hardy which makes them really good beginner fish. The pet store said that we should wait 1 week before getting any more. It's for the better of things, so we need to see if they survive well in their environment. Can't wait until Wednesday!
