DefStatic- ty, ty, ty
i will make the heater a priority then, the name of the pellets escape me but ive cut him back to about 6-8 a day. one gallon is an estimate after the rocks and plants but i think it is a touch bigger then that but havent given it a real measurement. if you look back a few posts, i was questioning if i was doing wc's too much at 25% every other day but i think what your saying is thats on point!
In a planted bowl like that, 25% every other day is more than fine. The biggest problem is since there is such little water, any changes in the water will be immediately effecting the betta.
They are very hardy fish, yes. But doesn't mean they can or should tolerate much. And i have seen some Bettas that just do not like being in a 4gal+ tank. Well, I havent seen them, but from talking to other owners. Someone just recently on a Betta forum was talking about they transferred their Betta from a 1gal to a 5 gal and the Betta didn't like it.
You will see some Betta owners (like any other pet) who think anyone who doesnt have a 3+ gal tank and use the most expensive food and stuff is not a worthy owner. My only fear with Bettas are people who put them in .5 gal or less bowls and do not cover it and do not do semi daily water changes. Or do not treat and test their water.
As for feeding, they are like most fish and do not know when to stop eating. A fair amount of Bettas die from being over fed. I use New Life Spectrum Betta Pellets. I had some Aqueon Betta Plus. The Aqueon is not HORRIBLE like some will make it out to be, but I did not like the inconsistent size of the pellets. And the NLS stuff is relatively the same price.
If you can find some way to ensure that the tank is staying at least 75 without a heater, I would say you are fine. 75 like I said is really the lowest you should go.
20% to 25% water changes every other day in a bowl like that, especially planted, should be more than fine. Just make sure you are treating the water appropriately.
Congrats on getting a Betta and providing it what looks like a great home!
