So I went to the Lfs today (how many stories start like this??? I digress) to buy some new plants for my 20 gal. Im trying to go all natural with no fake plants. (and I achieved it!) Well I saw a peacock eel for $6 (u.s.)!!!! and he was about 5or 6 inches!!!! so I bought him....been wanting one for awhile but always were a bit too much (normally like 20 bucks) SO now to the q's....I put him in the tank and did the "drip" to acclimate him. Then as soon as I released him he swam to the bottom looked around for a second and went under the gravel. Will he stay down there or when he gets comfy and cozy will he come out and hang around???
