I have a 225 litre discus tank all water parameters are fine. but i notice that my discus are flashing a bit ant night - is it best to start treating with Prazi? Also my smaller yellow one has two pimple like things on the lower edge oh its body - seems to be eating okay however, should I worry about this??
also algae is overrunning the tank its long, fluffy and kind of blue green, I have manually removed as much as I can and suck as much up as I can with a gravel vac each time, is there anything else I can do?
And lastly i have all these little spores kind of like minature four leaf clover things that have floated to the top of the tank, I am netting out as much as I can but it keep on cmming back, its some kind of weird plant growth? any ideas? HELP !!!
