About a week ago I got my first betta hurray! His name is Squirrel and he is a blue and white half moon. He greets me when I come home and is very active. I got him knowing that his fins were mildly damaged. I did think he had an anchor worm on his anal fin but I think it's just a piece of his fin that sticks up from damage. He is in a 2.5 gal bowl, with a heater that keeps the tank at 84 F on average, sand for substrate, and a variety of live plants. I use spring water because I'm not comfortable with tap and conditioner, and I do a 30-50% change every 4 days.
Here's my questions:
1. The food says put enough in that he can eat in 5 minutes, but I'm pretty sure that he'll keep eating even if I keep putting food in for 30 minutes. What's the max I should feed him per day (I feed him twice)?
2. I have freeze dried krill for my hermit crabs. Can he eat this if I break it up?
3. He makes A LOT of bubbles, is there such thing as a betta making too many bubbles?
4. He's always swimming in tight places like under roots that are sticking out of the sand and between leaves. Is this just him entertaining himself or is he itching (he doesn't have any visible problems even when I look with a flashlight)?
5. Without the heater the water is a steady 73. With the heater it fluctuates between 82 and 86. Which sounds better for my fish?
6. I would like to add snails to the tank (Petco has these neat big ones). What sort of extra care do they require? And by adopting from Petco do I run an extra risk of bringing bad things into my tank? Their fish ALWAYS have ick, it's awful.
Thanks for any answers! I'm currently hopping between temporary houses and I really don't want anything to get over looked. Once I'm in a more permanent situation I hope to upgrade his home and spoil him more.
Also, I'm super interested in this labyrinth organ, if anyone has info on that.
