I am new to having an aquarium and have water change questions.
I have a Fluval Spec V - five gallons. I added a fish a week ago today, a male betta.
1) I drew water a few days ago to do my water change with, it is 68 degrees. I am keeping the tank at 80. When I do water change, should I be heating the new water in any way? Won't a change of temperature stress my betta? I've been doing water changes while cycling and all the weeks the plants were in there without fish and never thought about the temperature I was adding to the tank. Now, with a Betta in there...?
2) The tank has a lot of plants in it. A local fish club member gave me starts of 15 different types of plants several weeks ago. I only have the one Betta in the tank. I have not seen any snails that would have come with the plants. Also, I feed pellets one by one - blood worms too... and the fish has eaten every bite as I give it to him - none fell to the bottom. With one Betta and lots of plants - will there be enough food for the beneficial bacteria to survive to allow the tank to be cycled? Am I correct in thinking that water changes won't affect the cycle, but will drop nitrate?
3) The tank numbers have been stable since I put the Betta in last Friday, and stopped adding small amounts of ammonia a couple days before that. I use the API Freshwater Master Test Kit. My well water tests .25 ammonia out of the tap.
So, for the last week -
ammonia is between 0 and .25 - it is just slightly colored
nitrite is 0
nitrate is 10
The plants are growing and rooting, and the Betta seems really happy, is active, eating well.
Should I do a 50% change once a week -- or more or less often? I was not sure given all the plants, and only one fish in 5 gal.
Thanks so much!
