I am going to Petco after work today to look for a betta! (I've heard the Petcos around here buy locally, which sounds good...) My question is about what I should do when I bring him home...
I have a 5g tank with gravel and live plants (wisteria, pennywort, watersprite, anubias) which has been up and running for a few months now. It has a heater and filter. I've been fighting algae a bit, so there's lots of fuzzies on the plants/driftwood, but other than that it's been quite stable. The water is clear, ammonia/nitrites/nitrates test at 0 (I guess because of all the plants). I do a 50% water change 1x/week.
My question is: is there anything special I have to do to acclimatize my fish before introducing him to the tank? What if the fuzzies are secretly EVIL BACTERIA waiting to kill my fish??
