@NeilD- well the other day my betta had this big red swollen spot and i told the petland worker and he said to use bettafix and he said its probably velvet but now my betta is better. Bad news (i think) is that theres weird stripes on him. but you can only see it when hes in the light (like you can see through him) he sorta looks like a tiger.
@Darkmoon17- well my betta is eating alot now and sleeping alot. he doesnt really look stressed to me but im not sure. btw i think my platy is a tetra i actually forgot
