The equation was a cubic equation, but for some reason my calculator won't solve it. Also, it seems to only want to solve easy quadratics. What is going on?1 AnswerMathematics6 months ago

The little line of white dots on the image. I can't get the picture to be any clearer, but does anyone know what they are. They are like flat snails with the big shell and instead have a hard flat shell like exoskeleton with their body against the glass. The little things don't bug my fish but they are multiplying like crazy.1 AnswerFish8 months ago

I know ghost shrimp is an all encompassing term for a species of shrimp. I want the ghost shrimp that is passive and don't go after my betta.
I bought about five "ghost shrimp" from pet smart to help me maintain my betta tank because the two I bought for trial did a really good job. Two weeks after I added the new ghost shrimp into the tank I saw my betta fin began to rotish. I thought it was rotting so I began adding almond leaves, but today I saw one of my ghost shrimps latch onto my betta's fins. I currently pulled out all my shrimp, and did a little research.
Apparently, there is a whisker shrimp that is a ghost shrimp look alike that will attack your fish. I just want to know what discerns them from ghost shrimp so I can remove it quickly.1 AnswerFish9 months ago

I have a Honey Gourami and she doesn't have the other eye. I want to know if it will be okay or will I need to give it special attention.?
It looked as if the eyes have been completely. There is a socket there and my fish will go out of balance every so often it gets right back up. She seems is still vibrant in color but a little pale. We just go there and my other fishes too. I have isolated her for now from the other fishes. Please tell me if she is okay or it is something serious.1 AnswerFish5 years ago
