Yes it is a golden CAE, I have 2 in a 46g tank with 9 female Bettas. In an aquarium setting they rarely get larger than 6". I have plenty of plants, caves & make sure they're well fed. So far no problems. I've done a lot of research on them & have gotten feedback from others who have them with no problems. I keep an eye on them & if I start to have a problem I'll take action. I love them, they're cool fish.
Sometimes she does if I don't stop her in time. I have 5 dogs so I'm pretty conscientious about barking unnecessarily. She barks at people she doesn't know when they come in the house & it can take a awhile before she settles down. Usually if they start playing with her she'll stop. And yes she's shy with people she doesn't know, she actually is a biter if someone just goes to pet her or pick her up. She has an orange caution sticker on her medical records at the vets.
