Thank you for writing I really appreciate it. If she is impacted by gravel, She most likely will not pass it huh ? I kindly appreciate all that is said to me, Thank You! I always rinse my filter before adding it. But I did not do it this time. As for changing the water, I will every few weeks. I do NOT do a whole water change, I will vacuum the bottom until about 8 inches down give or take some. I am aware of the tutti frutti as it is albino, I do not like the fact of the dyeing thing but I sadly thought they are injected with the dye. I added my frogs after I had the fish. I have some tiger barbs,giant danios a pleco and I forgot the other one. The frogs seem to have no interest in them. I added some rosey red minnows & they went after them. I now found out to not feed them though. I turn on the light when I feed the fish & to give the plants some light. But the frogs do have darkness for when the light is on. & her vent looks like a girls vent as I seen on photos & as for reddened or swollen I myself really does not know if it is a normal look or not for her. Another thing I`d like to add is, I hand feed them mostly they are very familiar with me, one of them always swims in the palm of my hand & just lays in there lol in the water that is. & they let me with no problem pet them and rub them.
