Emerald File Fish Monacanthus Ciliatus
Overview
The Emerald File Fish, scientifically known as Monacanthus ciliatus, is a unique and striking marine species known for its vibrant green hues and velvety texture. It is a relatively small fish, reaching up to 5 inches in length, and is characterized by its elongated body and small, retractable spine on its dorsal surface. This fish is a master of camouflage, blending seamlessly with its surroundings to evade predators.
Origin
Native to the warm, tropical waters of the Western Atlantic Ocean, the Emerald File Fish can be found from Florida and the Bahamas, down to the coasts of Brazil. They prefer reef environments, where they can hide among corals and sponges.
Feeding
Emerald File Fish are omnivores with a preference for algae and small invertebrates. In an aquarium setting, they should be offered a varied diet consisting of marine algae, spirulina, mysis shrimp, and brine shrimp. They may also nibble on small polyps of certain corals, so it's essential to monitor their feeding habits in reef tanks.
Tank Mates
This species is generally peaceful and can coexist with a variety of other fish species. Ideal tank mates include small, non-aggressive fish such as clownfish, damsels, and gobies. They should not be housed with large, aggressive fish that may intimidate or harm them.
Aggression
Emerald File Fish are typically not aggressive towards other fish but can become territorial with members of their own species or similar-looking fish. It's advisable to keep them singly or in mated pairs to avoid conflict.
Experience Level
Due to their specific dietary and environmental needs, Emerald File Fish are best suited for intermediate to advanced aquarists. Caretakers should be familiar with maintaining stable water conditions and providing a varied diet to ensure their health and wellbeing.
Water Parameters
  • Temperature: 72-78°F (22-25.5°C)
  • pH: 8.1-8.4
  • Specific Gravity: 1.020-1.025
  • Alkalinity: 8-12 dKH
The Emerald File Fish requires a well-maintained tank with plenty of live rock and hiding spots to thrive. Their tank should also have a tightly fitted lid, as they are known to jump when startled. With proper care, this beautiful fish can be a captivating addition to any marine aquarium.

No match for 3 month old puppy!
Color: Blue
I was really hopeful this would last a while, but 5 minutes out of the box and my 3 month old puppy has chewed two chunks out of the blue part already - seems this is too soft for puppy teeth, and it specifically claims to be good for puppy teething. 5 minutes of play is not worth paying for. Maybe if the material had been more substantial, this could have been great for high activity level puppies. My pup had no trouble carrying it around, so it wasn't too heavy, and it was easy to play fetch with as well. For reference, my pup is a mixed breed - labrador, poodle, newfoundland.

Best ever dog toy
Color: Pink
This is such the clever toy and actually I think it makes my pup more clever too. The ball is tough enough to withstand excessive chewing. I really can’t say enough good things about this particular dog toy. This will keep my dogs attention for such a long period of time and you can truly just watch the wheels turning in his head as he figures out how to get the food out would buy again and I probably will just to have a back up.

Great for 22 pound mini schnauzer/mini greyhound mix
Color: Pink
I have a dog that is half miniature schnauzer and they love to sniff and snuffle. He is enjoying this ball. I put the little freeze dried liver cubes in it and he will play with it until he gets them all out, and maybe keep playing for a bit. I can't give it 5 stars because I don't know quite how I'm going to clean the inside of it. I can't speak for how well it cleans his teeth because he hasn't had it that long. It is sturdy. He's a 22 pound medium size dog and I'm confident he cannot chew it to the point of destroying it. He's barely made a scratch on it so it may break down over time but it's not something a small or medium dog should be able to chew through the first day. He's had it about 2 weeks and we use it every day and it's holding up very well. It's not interesting enough to him to play with it without treats in it but he rarely plays with a toy unless I'm actively playing with the other end of the toy or throwing it for him to chase (part Italian greyhound too so he does like chasing) but he will get excited when he sees this ball as he knows treats are going to be in it. This one is a good size for him and he can pick it up with his teeth. (This is the hot pink one with the blue ball inside) Definitely worth the price if I can figure out how to sufficiently clean inside of it. So far rinsing with warm water seems to keep it hygienic. It's silicone so everything pretty much slides out. I wouldn't put any moist treats in it though. It's quiet. No squeaker, but he has plenty of toys that squeak and we didn't get it for that. It definitely appeals to his sniffing and snuffling instincts.
