I just got a new Betta yesterday at the pet store. He is a lovely blue Crowntail male, I've named him Sapphire. :) Though I have had Bettas before, I have already learned he should have a heater. I'll be going to the pet store after work to get one.
Anyway, I have some very nice cleaned & disinfected sea-shells I was thinking about using as decorations. Are they safe to use in a tank? I don't know why not, but then again I am not an expert. I don't want to harm my new fish.
Thanks so much!
