My 5 Gallon
betta tank was a new experience for me. My university limits tank size in a residence room at 5 gallons or less, so I bought a 5 gallon tank, Elite Stingray5 Filter and Elite heater, and the other tank basics, as well as a Male Betta.
Tank Layout #1: Circa September 2009
Then after multiple tail-shreddings on the plastic plants, I purchased some silk plants and did this:
Tank Layout #2: Circa January 2010
But I was getting tired of the Ornament... I wanted something different... After a trip to the dollar store, I came up with this:
Tank Layout #3: Circa Late February/Early March 2010
But hey! Now I want 2 Bettas... A divider and $20 later... and Here is the current tank layout
Tank Layout #4: Circa March 2010
My Bettas:
Alpha Houdini the Veil Tail: He's a chronic tail biter. This was last week before he chomped off the majority of his tail. Thankfully, it regrows in a few weeks. When he has a tail, he's a Red (but looks Magenta) mottled with purple bodied-Betta with Purple metalic highlights on his body and fins
(Name is still pending decision.) So far he's being referred to as Chomp Cemlexarahey (Chem-Lex-Air-Ah-Hey; a combo of 4 of my friend's names): A fairly new and energetic addition to my tank (as in, added yesterday). He's a red/blue/white metallic-like Crowntail.

(One pic doesn't do his colour justice)
