When you're broke, have a full schedule, and enjoy your sleep, you learn to control yourself!
I have 2, one waiting at a breeder. Those are my 3 and that's that. Maybe one more female, but no more. YES I see tons I love, YES I have the urge to buy more, YES I have to control myself. But I don't have a problem with extreme impulse buying.
First of all I know I will need to pay for them, their tank supplies, and now their filter cartridges and other misc items monthly.
Second I think of how long it takes me to do water changes already, and if I would like to add on at least 30 mins longer per week for this new fish's water changes.
Third I consider if the novelty will wear off. Why am I impulsing? Do I really want this fish or is it because I just want one?
Lastly, I ask myself if it would be fair. I have my 2 and my community tank and already they are lacking... I would want my 2 bettas to ideally be in 5 gallons a piece with better decor and set-ups. My community is so lacking due to my lack of funds! It isn't fair to the ones I have.
I bet if you thought of all that before buying, you'd save yourself from impulsing like that! I know many members who LOVE having 10+ bettas, though, and love buying new ones, so to them it isn't a 'problem' but a loving addiction ;) I am one to love few rather than many... I know if I had 8+ I would lose interest and they'd all suffer... but that's just ME!
