The remaining goldfish also had their fill. The pellets floated at first but would sink when disturbed by the fish. This has to be the best buy out there! It's a huge container and it lasts a long time for my catfish and pleco's.
I like this formula because it takes a while to break down, it get's eaten up before it sinks into the gravel. I've fed my fish the Wardley brand for years and the fish seemed to really like it but most of it got wasted into the gravel and I had to clean more often. I mix this up with the Wardley premium pellets, they eat the Wardley's up quickly and the API pellets stay in longer so they always have something to munch on.
My fish seem to be happy and their belly's are always bulging. Hikari 3 Pack 8. Thompson Chicago. My fish love it and it does not discolor or cause a foul snell in my gallon tank. My Fish love this stuff. Everything in the tank: Angels, Chinese Algae eaters; Spotted Raphael and Bumblebee Catfish and even the Plecostomus rolls out of hiding like you rang a dinner bell.
Only 4 left in stock - order soon. I have been feeding this food to my gold fish for over a year now and it is the best gold fish food I have found so far.
Since I began feeding this food to my fish they have put on good size and their color are vibrant. The package appears small on the picture but you do get a lot of food for the price. Omega One Cichlid Flakes. The fishes eats it, the fishes gets bigger, and the fishes stay alives.
African cichlid fish: a model system in adaptive radiation research
Currently unavailable. Great value! Lasts a long time! The capability of color discrimination in cichlids can have a big impact in understanding the natural history of this speciose clade because cichlids' visual capabilities and coloration patterns have been associated with their adaptive radiation and evolutionary success. We thank all the members from the Carleton and Kocher lab for taking care of the fish throughout this project.

JEB is partnering with the Big Biology podcast and in this sponsored episode , JEB Editor Michael Dickinson talks to the Big Biology team about the aerodynamic mechanisms of insect flight, how insects control flight with their tiny k neuron brain and his recent JEB paper showing how fruit flies navigate using the sun and polarized light as a compass. Invasive lionfish are a colossal problem in the Mediterranean Sea and western Atlantic Ocean.
Now it turns out that they are successful invaders because they invest more energy in digestion than moving about.

Daniel Escobar-Camacho. Experiment 1: binary choice The first experiment consisted of a binary choice test where fish chose between two cards with one color circle each, the trained blue stimulus was presented with yellow and gray as distracters. Experiment 2: multiple-choice gray To further confirm our results in the first experiment, we used a multiple-choice discrimination test.
Experiment 3: multiple-choice color Finally, for the third experiment, we wanted to know whether fish could discriminate blue from several different wavelengths and whether there was a bias against a specific color. Data analysis For experiments 1, 2 and 3, a one-tailed binomial test was used to calculate whether the fish could distinguish the trained from distracter stimuli.

Cichlid behavior Cichlid vision has been extensively studied using a variety of behaviors associated with visual cues. Color opponency and opsin coexpression Our visual modeling assuming a dichromatic visual system based on double cone summation predicted that cichlids would not be able to discriminate blue from gray. Color discrimination and the Weber fraction In this study, we wanted to take the first step in understanding vision in cichlids and to know whether they have true color vision.
Color vision and its relationship with cichlid ecology and evolution Our results are particularly relevant for the study of evolution in the cichlid lineage because the exploitation of color vision allows cichlids to use communication channels that can be subject to variation. Conclusions In this study, we have shown that cichlids can be trained through classical conditioning in order to perform color discrimination tasks.
