I added a group of five Penguin Tetra to my 60-liter tank. They are active and peaceful, and the black stripe is very noticeable. Easy to care for and they don’t stress other fish. Water parameters stayed stable with regular water changes.

The fish are lively and colorful. I kept them with other small community fish, but avoided long-finned species. They eat the flakes easily and seem healthy after a month.

Perfect for beginners. The fish adapt quickly and don’t require much attention. I feed them once daily with flake food and occasionally offer frozen brine shrimp.
