just out of curiosity... i was at petsmart today and i noticed (and not for the first time) that the boita angelicus is really REALLY pricey! almost 20$ any reason that this little fish is so much more expensive than its kin-fish? im prety sure i got my zebra loaches (bpita striata) for something like 3$ and the yoyo's for around 4$... just wondering.
