feeding fish cucumber first time

[cioscraps]

just fed my fish cucumber for the first time, the betta and platy have been all over it but my skirt tetras and my oto havent touched it

Tetras usually won’t eat cucumbers. The ottos should find it eventually.

my otocinclus don't really like cucumber, they prefer algae wafers, wood, decaying leaves, spinach, and lettuce. maybe try that
