i have a figure 8 puffer and his beak seems to be getting big. i give him snails and freeze dried shrimp. here latly he seems to not be eating as well and is loosing some weight. for last couple weeks the water temp has been up some of my other fish had ich. i did the salt and heat treatment and it went away. but my wife noticed the puffer looks to have buck teeth lol. what can i do? thanks.
