Blennies - Marine fish

Blennies - Marine fish are popular aquarium fish, and for good reason. They are peaceful, colorful, and many are downright helpful. For example, the aptly named Lawnmower Blenny will keep your green algae well trimmed and presentable. With the exception of Fang Blennies, Blennies are totally reef safe- in fact a reef environment is really best for them because they can be shy and the intricate rockwork of a reef provides ample hiding spaces. They are omnivores and should be fed a varied diet of frozen or live foods and plant matter. Blennies do not have teeth or functional jaw, so food must be small enough for them to swallow whole.
Blennies are often confused with Gobies, but there is an easy way to tell the difference. Gobies have two distinct dorsal fins, Blennies have a single dorsal fin that runs the length of their body. Also, Gobies' pelvic fins are fused to form a sucker, similar to Remoras.

Batfish - Marine Fish

Batfish - Marine Fish are gorgeous and striking fish that are not common in aquaria for one major reason: they get huge. A two or three hundred gallon tank is needed for one, minimum, and larger is better. They start out as tiny, manageable-looking cuties, which often fools aquarists into purchasing them for their small aquariums. However they quickly grow to gargantuan proportions, and require large amounts of food as well as space, so beware. They are not reef safe and should be fed plenty of large meaty foods. Batfish change greatly as they grow, however the potential aquarist is most likely to see them in their juvenile form, so that is the description of the colouration here. They all have generally the same body shape: disk-like with tall dorsal and anal fins, similar to a Freshwater Angelfish.
