First of all thank you very much for an awesome forum and cant express my words for the precious members here devoting their time. This is my first time with Fishes,and discovered this forum. I have started small with 5.5 Gallon aquarium- i did my basic research and with the help of amazing and kind heart lady at Pet Smart - I took aquairum and put gravel some artifical plants and kept the filter running for 4 days and keep on adding the liquids the lady suggested Quick Start and Tap Water Conditioner..and on 5th day i got 2 Sunburst Platys..and the lady advised the water is bit low on ALkaline side and wanted to still add the liquids for few more days.. The platys we made sure got only Female and also not carrying any babies, today was 8th day we had fishes.. out of two i have observed one was very active and the other being moderately active and sleeps more resting on the gravel.. initially the both dint get much together and maintained distance. First few days we used Omega One Super Color Flakes ( we took small pinch , crushed into smaller pieces put into water and added to the aquarium) .. they ate Food good for 3-4 days after that,, they are just eating a small flake and spitting it out eventually.. and becoming bit dull..and they are sleeping and all more from few days.. and yes i making sure i turn off the aquarium lights at nights to let them sleep.. From yesterday or so.. they are getting both very much together.. and spending most of the time together on the gravel.. and i have to go and make sure few times tapping the aquarium and they are moving around.. even i am adding food they are not coming out that much..and on continous tapping they eat a flake and spit it out.. I am very very very very concerned about the fishes and dont want nothing to he happened to them..and like to be more healthy and active.. yesterdy we even changed to Tropical Fin food and the ate a bit yesterday..and today again they are not interested to eat.. kindly please advise what should be done.. we took water for testing yesterday..and they said it bit low on PH side and given us PH up which i have added yesterday..
