The Albino Threadfin Acara is a striking fish with a clean, elegant appearance. It’s active in the midwater zone and eats a wide range of foods. I feed it a mix of frozen and vegetable matter daily, and it thrives in a well-maintained tank. Very easy to care for and adds visual interest to the aquarium.

This fish is quite peaceful and doesn’t compete with other species. It shows good color development when fed a varied diet. I noticed the females are noticeably fuller than males, which is a good indicator of maturity.

I’ve kept this species for over six months and it remains healthy and active. The fish enjoys both live and frozen foods, and I’ve seen it eat shelled peas regularly. It’s a great addition to a community tank with proper water parameters.
