Dalmation Molly(female & the dominant fish of the tank)-Woo,
orange Molly-Maude Lebowski

Blood fin Sword-Donnie, red tux sword-the dude
Dwarf gourami-Gunther, blue neon Gourami-Walter Sopcheck

The Ottos(2) because i can't tell the difference

and then the Glowlights and the white clouds who all hang together
