Thanks for the replies
. I figured but hoped growing enough bacteria in the substrate might actually work
I don't know how to differentiate "survive" and "thrive" but I had a beta for 3 yrs at work in a 1 1/2 gallon tank and he is still alive (I moved so now a co-worker has him). But when I lived in South Florida, a heater really wasn't needed. Once again, I don't know much, so may-be the little guy is suffering. I did water changes once a week and added a half tsp of aquarium salt.
This current betta, "Jack Frost" was a birthday present for my 4 yr-old son from his grandpa. I've had him for two weeks now. I bought an API ammonia testing kit (the little jar with the two liquids you drop into it, shake, and wait 5 min) ... according to that, after 1 week, the ammonia level is at 0.25 mg/L (I did a 75% water change after that reading). I did do a 25% water change mid-way through the week. I'd been changing the water every two days, but then I read about checking ammonia levels and using that to determine how frequently to change the water and how much of the water to change each time(which is why I bought the ammonia testing kit). It's not laziness about changing the water, but it just doesn't make sense to me that Jack would NOT get stressed being moved around every day.
The water temperature ranges from 76F to 80F without a heater, though I am lookinging into one for the winter. I have a 5 gallon tank but that is housing two african dwarf frogs. That aquarium is in a different room and does need a heater right now. I have a Hydor 25 watt heater in that tank, do you think that model would be OK for the smaller 2 gallon tank? (I don't want to cook poor Jack).
May-be I can get a 10 gallon tank for x-mas or my anniversary in November ... but I think my husband has had it with my pet expenses this past month (I've spent around $200 mostly on the frogs). When I do get that 10 gallon (I'll look on craig's list or something and see if I can find one cheap prior to November) I'd like to make it a community tank with Jack and the two ADFs.
I've heard about bio-load ... but according to that, 1 gallon is enough for a betta. Do you think I could keep a few more things (snails/friendly fish/aquatic frogs) in a 10 gallon community tank - or would the betta and two ADFs be the limit?
Thanks for all the help! I really want to be a responsible pet owner and model that behavior for my children.
