You know there are just people out there who think because they have all the money in the world they're just somehow better--and that's okay! Everybody has different opinions and outlooks, and some people really DO think money is "everything" while others (like myself) believe love and care is all you really need.
Heck, yesterday I browsed PetSmart and found a 20 gallon on sale for $30 due to no hood/light (I guess it broke??) and SNAGGED IT UP! Before then I had 2 mollies and 1 glowfish in a 7 gallon, which people bashed me all over for. You know what? Those fish LOVED their little set up, were always active, eating well, not a sickness in site. Now with the 20 gallon I bought them some lovely females! ;) Going to add 2 more glowfish then capping it off. I think 5 mollies and 3 glowfish is enough for that 20 gallon! (Maybe some frogs or crabs later on... We'll see!)
Thing is, I purchased a filter for a 15 gallon at Walmart for $10. Guess whose filter is a BEAST and filters this tank like CRAZY!?! MINE! For a 20 gallon filter it'd be $20. Pssshhh, who needs it? Also, I have seran wrap covering the top... Don't tell! haha! I'll buy a real top one day, maybe with a built in light and filter, who knows? All I know is I'll be building me a stinkin' stand sometime soon, use my lamp to give them light, and that filter and seran wrap will keep my fish well cared for until then!
As for my world in the bettas, I will be purchasing a male soon most likely half moon. Looking now(: I don't have much, just that 7 gallon with a filter missing the grated piece at the bottom so I bought some plastic piping and will silicone it to the tube and saw in some grates. I'm so cheap! LOL! Then I'll put my new betta in there with some sand ($4!) and a plant for now.
Once I gain more money then I'll most likely buy him his own tank (1-3 gallons) to fully decorate nicely (sand, river rocks, silk plants, driftwood!) for him to enjoy all to himself. I'll buy a nice little filter made for 3 gallons to help me out, because some nights I simply don't have the energy for such frequent water changes. (BUT I'M SO OCD ABOUT IT!!!)
POINT IS, we all have our love and obsession for fish. And most of ours are extremely well taken care of without sickness and have pure happiness! Some of us have really nice fancy tanks with hoods & stands, others (like us) have smaller discounted tanks using random things to make it work, LOL. But in the end we're all going to have happy little fish and we're all striving to make their homes better for them daily.
If I had money, I'd buy the 50 gallon I want in a HEARTBEAT and another 10 gallon for my future betta friend to divide in half for another. But, I have other priorities (can we say attending a wedding in another state?!) and such. *sigh* I'll get my income back soon!
Do NOT feel bad! You have gorgeous fish who ARE happy & healthy, and that's all that really matters!!
