The swordtails are vibrant and active. They adapted well to my 10-gallon tank after a week. I added some plants and kept the water clean. They swim freely and seem healthy.
Tim Underwood –
Good coloration and lively behavior. I noticed males chasing each other, which is normal. The tank needs space, but they are not aggressive with other fish.
Victoria Thomson –
Easy to care for and very colorful. I kept them with tetras and they coexist peacefully. Water parameters stayed stable after a few weeks.
