It is Bacter boost a Weiss company product,supposedly it works have tried it out at work and seemed fine though i will get my water checked today.
Was going to go for groud cover but i thought the threadfins would dig it up as would the fei feng. Found a really active pictus cat so he may swim so much it wont grow.
You will get pics of the fish when they are in, any suggestions for showy midwater swimmers was thinking bleeding hearts, congos or african red eyes, any better ideas appreciated.
