hi there i shall try answer all thoughts and questions on bettas
1 do not keep more than one male betta in a tank...and dont put a female in with him for company, he'll kill her...most important rule lol
Alrighty, got it.
2 feed once a day...mini pellets, fish flake, and once a week..tubiflex/bloodworm/brine shrimp..either frozen, dried, or live...if dried food is given, add a deshelled pea once a week
I have some frozen bloodworm so that works.
3 lots of real and/or silk plants..not plastic as they tear fins
I'm not really a fan of plastic plants anyways so 
4 gravel or sand either its your preference
I currently have gravel with marbles
5 heater, sponge filter, and yes stocking over inlet..great.
Yeah, I already have a stocking over it because I used it for a fry tank for a while
6 water change every time a fluid water test kit says ammonia or nitrite about 0.25ppm....with one fish in a tank your size once a week should probably be enough
Water change once a week, okie dokie.
7 they like hidey holes, caves, coconut caves, rocks to hide behind or shelter in, ( arranged like flintstone house)
O: awesome. I love the coconut cave idea!
8 they don't really like tankmates..i have golden apple snails in with mine, and some have had success with pygmy corydoras or norman lampeye fish, nothing with big colourful tails/fins as he'll see them as a threat.
No colourful tank mates, alrighty. I was thinking of maybe some of the pygmy cories, but I'm not sure if they prefer a sand substrate?
9 they love your company so spend time talking to him. My Blaze allows me to stroke his belly a tiny bit. and will come up to my finger to feed ( not take off my finger but almost there)
Oh wow, that's so cool, well, he'd be in my room just at the bottom of my bed so he'd get company, can they tolerate the presence of a cat? Because my cat literally lives in my room but he's very calm and has no interest in my fish, he just likes sleeping on top of my other tank.
10 Bettas have a number of tail types,... veil tail, crowntail, combtail, spadetail, platkat tail, double tail
What's the difference between them?
11 bettas have a number of different tail fin type...halfmoon, delta, superdelta, there probably are others i cant remember their names
Ditto ^
12 bettas have load of colours, single colour, bi-colour, tri - colour, marble, butterfly, dragon,
if you go to eBetta.com ( i think thats its name..you will see).
