Hi Everyone

I've got really bad cyanobacteria in my little tank. I'm hoping to lose it when the fish go into the new large tank, but i've got to wait until the temperature is right - which is turning out to take longer than expected cause I turned the heater the wrong way and it's now at 80 instead of 72!

Hence the delay. The BGA looks dreadful, but will it actually harm the fish?

It's a 10gal with 5 danios, 5 WCMM and 1 oto - was 3 but I've lost two in the last week which is what prompted me to ask. I've been feeding them cucumber but only the survivor was interested.
 
yes it is highly toxic to fish if they ingest it.
