You are right i hate the sand and it will be removed as soon as i find the right replacment but the old gravel i used to use is now banned from use as to much of it was taken from the shores
as for finding them i just look for tigers that are sort of stable and chances are they will become full stable when added to a tank with good water
this guy is about 8inch
i have a thin bar coming in a few days and that will complete the set ST IT NTT NGT i wont be buying AT as they are a brackish water fish and my tanks not brackish
all new tigers are being dumped in the main tank as in the past i have found small tigers mix with most fish
