Some pics I’ve taken recently of my PetCo rescued betta (veil tail) I thought were nice!

6 gallon tank
Sponge filter
Heater @ 78°
3-5 Snails
Rotala
Java Fern
Frog bit
Driftwood

Question - if his fins have become more transparent/white since getting him, is this a bad thing? I know bettas can change color but I thought that when they’re happier they become more vibrant. He seems to have lost some of his red but his blue is more vibrant. It doesn’t look like fin rot or anything bad from what I’ve researched, experts please let me know!
