My best friend decided to name my original guys:
Red guppy - Pischnikity (Pish-nick-it-ee)
Yellow guppy - Melfusious (Mel-fuce-ee-us)
Marbled angelfish - Alfred
Colombian tetra - Ringo
Scissortail rasbora - Star
Neon tetra - Neo (yes, we love the Matrix)
Black widow tetra - Barney
Kribensis - Alouisius (Al-oo-ish-us)
I later changed Alouisius's name to Manson (after the serial killer, coz she was so dang psycho), but her & all but the colombian & black widow died off
Each now has 3 friends - the colombians are named the Smurfs coz they're bright blue with red tail & fins (Papa Smurf's the biggest, original one; Smurfette's 2nd biggest one, often hanging around him; Brainy Smurf's the 2nd smallest, who always knows when there's food around first; & Baby Smurf's the smallest). The black widows are the Rubbles - Barney (the biggest), Betty (2nd biggest), Hoppy (the Rubbles' pet, my 2nd littlest guy), & Bam-Bam (the baby).
Ok, so they're weird names but I reckon they're cute.....all will be fine untill they get to the same size lol.
