Question
i just emptied a 5.5 gallon fish tank and have deceived to plant cactus in it do you have any suggestions.

Answer
Giles,

You'll want to plant cacti that stay small (mammalaria for example). Since no water will drain from a fish tank, you must make sure you don't over water and lastly, run a grow light for at least 12 hours per day, otherwise the plants will grow funny looking. Hope this helps.

Sincerely,

Greg
