Two Stripe Lyretail Killifish Aphyosemion Bivittatum 3cmOverview: The Two Stripe Lyretail Killifish, scientifically known as Aphyosemion bivittatum, is a captivating addition to any freshwater aquarium. This small, yet vibrant species is renowned for its striking coloration and unique tail fin shape. Males display a dazzling array of colors, with two distinct longitudinal stripes that run the length of their body, complemented by a lyre-shaped tail fin. Females are subtler in color but share the same elegant finnage. They typically reach up to 2.5 inches in length, making them a perfect choice for nano and community tanks.
Origin: Native to the dense, shaded streams and pools of Central Africa, Aphyosemion bivittatum thrives in environments with plenty of plant cover and soft, acidic water. Their habitat ranges from Cameroon to the Congo, where they are adapted to life in fluctuating water conditions.
Feeding: Two Stripe Lyretail Killifish are omnivores with a preference for live foods. Their diet in the wild consists of small insects, larvae, and crustaceans. In the aquarium, they can be fed a variety of foods including live or frozen brine shrimp, daphnia, and bloodworms, as well as high-quality flake foods. Regular feeding of live foods can enhance their coloration and overall health.
Tank Mates: Being peaceful and somewhat shy, Aphyosemion bivittatum does well with other small, non-aggressive fish. Ideal tank mates include small tetras, rasboras, and other killifish species. It's important to avoid housing them with large or aggressive fish that may intimidate or harm them. A densely planted tank with plenty of hiding spots is ideal for these fish to thrive.
Aggression: This species exhibits very low levels of aggression and is often more likely to be on the receiving end of bullying from larger, more aggressive tank mates. Males may show mild territorial behavior towards each other but rarely cause harm. Providing adequate space and hiding places can minimize any potential stress.
Experience Level: Aphyosemion bivittatum is suitable for intermediate to advanced aquarists. While not the most demanding species, they do require stable water conditions and a specific diet to maintain their health and coloration. Knowledge of breeding killifish can also enhance the keeping experience, as they have fascinating breeding behaviors.

Great except for one small flaw
Color: Regular - Beak, Color: Regular - Beak
Our dog likes to get at the juicy innards of every toy we buy him. We tried this one as it promised to be "bullet proof". It lasted about a week which in fairness is 6.5 days longer than most of the toys we buy last. He ripped off the wings which was to be expected and not an issue. It took him another 6 days to finally locate a weak point and break in. It appears that the tag is not made of kevlar but merely sewed on. I guess it would be better if they had just sewed it on top but they made it part of the overall structural integrity. This provided a small area of weakness which our dog located and proceeded to exploit. It's like having the death star but installing a small thermal exhaust port that allows for access to the very core of the station. Makes little sense. Overall I am pleased with the overall sturdiness but in the end this toy had a small design flaw that my dog was able to locate and exploit in his neverending quest to gain access to and eat polyester fiber stuffing

STRONG AS A MONSTER (albeit a cute one)
Color: Large - Billy the Beast Monster, Color: Large - Billy the Beast Monster
My aggressive chewer ate the adorable monster's ear off on the first day, but who cares? The body of the monster has been indestructible so far (one week). My 7 month old pup cbews it for a good 10-15 minutes at a time several times per day. Great quality product and outlasting all the other toys I bought (which she destroyed in 10 minutes - even the ones rated "Level 4 toughness" from Walmart. I think it's hilarious in my photo that the monster's expression perfectly shows his disappointment about missing an ear, LOL.

King has met his match.
Color: Large - Billy the Beast Monster
I received my dog's toy this evening when I place the toy on the ground my dog King went crazy. He is a one-year-old Pitbull and love to tackle any toy he believes he can't take down, but Mr King has met his match with this toy. He was using all of his bite force to demolish the toy but the toy actually has worn him out. He ran around my yard for about 30 minutes with the toy in his mouth producing the squeaking sound from the toy as well. Hold up the toy is totally filthy with dirt almost covering the entire green and yellow belly of the toy. I have brought king mini toys in the last couple of months and this is the best toy that holds up to his energy level. I tried to retrieve the toy and place it in his dog house because it is far beyond his bedtime, but he wanted to play catch me if You can with my new toy. This is a great toy for those big energetic dogs that love to take their aggression out on maybe some furniture or perhaps that favorite shoe you do not want them to chew on. I am totally sold on this toy I brought from the seller who placed the items on the Amazon site. I plan on purchasing a another toy from the buyer to keep King energy at a low level if I can. I just checked on my dog and he actually has taken the toy with him inside of his dog house and now the toy is snugged under his left paw. I'm one of those smart owners I'm not going to even try to take it from him tonight but hopefully in the next week I can sneak it from him and it may be perhaps wash it. I did this item AA Plus

Cute, but not Maligator-proof!
Color: Small - Towering Timmy Monster, Color: Small - Towering Timmy Monster
Fun toy while it lasts. My Belgian Malinois made quick work of this little guy but still enjoys playing with its carcass. Bite Force* but not taking into account the bite force of a Mali-gator!
