I have has many Betta over the years but after finding this forum and lurking for a few months I finally have what I would call a "proper" set up.
( DISCLAIMER : I know this is a matter of personal preference and everyone finds what works for them as far as tank size, filter, heater, water parameters, food type and so on, so please feel free to make suggestions or critiques but keep it positive please
The most important part, the fish! I went to my LPS about 2 weeks ago, I intended to get a small furry animal, instead I came out with the most beautiful orange/pink crowntail male I have ever seen. He was very active, even in the dirty little cup he was housed in and has the cutest little metallic scales on his gill flaps. I had no set up so unfortunately my poor little guy spent the first 4 days in a 1/2 gallon with just a silk plant and a 1 hide-y hole left over from my days of improper betta care. I picked up Betta water conditioner and some Betta gold pellet when I purchased him.
My boyfriend named him Rokusaburo Michiba, anyone familiar with the 90's TV show Iron Chef (the original not the "America" version) will remember Iron Chef Japanese Michiba. I shortened it to Ro. I found a 5 gallon tank and 50 W heater on craigslist sold as a bundle for $20. I have no filter, do not intend to get one, I do 50% water changes every 3 days currently. Once again please understand that this is my personal preference and what I have found works with my situation and water condition.
That being said Ro's tank has 1/2 gravel and 1/2 bare tank, 2 silk plants, a Betta hammock, 3 glass hide-y holes, and a thermometer that my boyfriend says I check obsessively (since the heater is used) to be sure it maintains a steady 79 degrees. I also add rooibos tea to the water because Ro loves the brackish water and I believe the tannins do work to boost his immune system and repair his fins which have some minor problem spots just from rough handling before being adopted.
Some of Ro's little Betta-nality quirks are "surfing" his heater, being a bubble nest perfectionist, and throwing a Betta temper tantrum when daddy feeds him, tehee.
I will post pictures as soon as I figure out how, I'm a little technologically slow for being in my mid 20's. Ha!
Figured out how to add pictures! Ro is the fish in my profile picture, that is him the day I got him in his pathetic little .5 gallon, will upload a better picture as soon as I can get one, he is a hyper little guy and likes showing off his pretty fins to mommy rather than pose.
