Cleaning Convict Tank

My convicts had babies while i was gone on holiday:bigsmile::bigsmile:.
but now it has got so much algae in it ,but how do i clean it with the babies in?

 

Were is the algae? If it is on the glass I would use a new dish washing sponge (not the ruff side) and wipe the glass. Otherwise if it is on your decorations, i would take some water out when i do water change and then rub them in that water and then put them back and new water (if you know what i mean).:bigsmile:

 

If it is tough to rub off with a sponge / rag ... Use a credit card.
