Had a Purple Wolfish that would rest in a plastic shower caddy used for Pothos plant root protection lol. Made me smile everytime I seen the Wolf resting in the roots.For my Ery ery, whether its floating or planting, he/she don't really care. In fact, IME ery ery loves plants, where he/she can hide (esp from light) and minor digging for food when hungry or find good place to laying around.
