Basa? That is the worst choice for fish you could ever make. Farmed in asia. Say no more.
Go for local fresh caught ocean fish, preferably temperate or cool water species. That means snapper, whiting, fresh tuna. Not salmon. Thats all farmed as well.
Veganism is a cult. They might be nice people but their brain is one track and extreme. Remember, these are the people that wanted to build a fence in Africa to divide the herbivores from the predators. Or have very sick dogs and cats because they don't feed them meat, their natural food.
