Is there any one oscar lover ? Anyway , i love mine . He is about 8" long and sharing his tank with same size flowerhorn with divider . Last night i heard a noise of a big " splash " . I ignore it bcoz many times oscar had jumped for cockroaches inside . But on morning when i see them , they are in same part . Flowerhorn was quite clear but oscar ! Dude , he was teared out from fins and some scratches on body . I have added yellow liquid to prevent fungus . My friend told me to use oxytetracyclin tablet . I heard this medicene first time . I onlx want to ask that Does it really works ?
