Hi there guys, I've had my Axie (named Chansey) for about half a year now, and recently have upgraded her filter to a bigger one and it seems that she's a LOT healthier and happier, gills colour are better now too 
I was thinking of buying her a sponge filter, but in the end i am just a uni student and doesn't really have a lot of time on my hands when it comes to having to do frequent water changes...but i really would love for Chansey to be having more activity time in the tank, would airstones be of any use too?
By the way I've attached her pictures, 1st pic is from when i haven't upgraded her tank and her filter
The 2nd one is after ^^ I hope she's looking good, she's very active at night and her gills turn into a more prominent red hue too
She's an incredibly picky eater though, so I have an array of choices of food at home, her favourite is brine shrimp, I try to give her bloodworms but she sometimes look away, same deal with pellets too
