Yeah, I use Cucumber all the time. No Need to pre boil it first, just cut a bit off and weight it down, i use all old weights from plants I get from the LFS
great, thanks phishyphil, how much should I put in for the 2 of them roughly and how long do I leave it in there before taking it out? Will it affect my water?
I've just broken an algae wafer in half and dropped half of it in the tank. The guppies and platies are fighting over it! Dropped the other half in and they're fighting over that too! I'm shouting at them "it's not for you lot!"
Just place a small (1/2 Centimetre thick) slice in the tank and leave it for a day, then remove the left overs. Ussually they will eat the whole cucumber, but will not touch the skin for some reason lol
