well, i went to the extremes and did a 100% water change. took everything out; plants, gravel, etc. took some water out of the community tank and put it into a small plastic tank, put the guppies in to that (was looking a little cramped) and then, with the lid on, put that in the community tank to keep the fish warm and in clean water till i had refilled their tank.
the tank is looking very bare at the moment.
when i put the guppies back in, i was rewarded with 4 fry within 10mins.
will be adding stuff slowly to the tank.
Q. how do i make sure there is no algae left on my plants??? they are currently in a bag, floating in the community tank. i don't want to end up throwing them away as i have a clump of java moss about the size of a tennis ball that i don't want to lose
