I have had the same three fish for about four years. I bought them for about 50 cents a piece and they were tiny little guys that I thought would be good fillers. Over the years, they have grown considerably and outlived all the rest and for about a year have been the only ones living in the tank. This leads me to my questions. The first being, can anyone tell me what they are:

And my second problem is, I have been having trouble keeping other fish with them. I haven't seen them being aggressive to each other but I have had a few random deaths and one fish that hides so much I thought he was dead. These are the other fish

This one hides:

Also, there is a snail who I think just died... Any help on what fish to mix with them and what to stay away from would be great! Also, is there a way to ensure a healthier snail?
