新しいメダカ飼育の楽しみ方！BON Style（盆スタイル） https://www.facebook.com/tabaca.magno?hc_location=timeline... no translation of text, but tons of pics of this and others.

Phreatichthys andruzzii, blind cave fish from Somalia. Check out those freaky blood-filled sacks where it's eyes ought to be. Is that crazy or what?
