My discus are with their fins closed all the time and some of them are no
coming out they are always hiding, I just got them 4 days ago, but before
that I had 2 nice snakeskin in the same tank but thay died because an
overdose of CO2, thanks to my Yeast DIY CO2 system, I change half of the
water and after 6 days I got 4 small ones, 2 snakeskin and 2 pigeon blood,
they are about 1,5" in a 33 gallons tank... can it be because bacterial
infection, or is just because they are new in the tank??? (the first pair
was nice looking after 2 days), and how much food should I feed them, frozen
food a mix of bloodworms and brine shrimp with Zoe (vitamin) and Garlic
Guard... 1, 2 or how many cube of frosen food???


Thanks
