well i havent fed my aro since 3-4ish pm today now its 10pm and decided to try the hikari sticks. Since these sticks are for a larger aros i had to break 1 stick into 3 pieces. He went to them right away circled them and ate 1 piece at first i was so excited i looked away for about 5 min to wash my hands and there isnt anymore in the tank!! 1 stick should be enough for such a small aro. Im going to try again tom bc these blood worms stink and the left overs just squiggle at the bottom of the tank. haha
