Sorry if I posted this twice. Had a glitch. Thanks for the compliments.
The guppies are from my 20 gallon. They kept breeding so I put some in the 55 gallon. After a while I had too many so I put the oscars in to thin them out. After the tank cycles I will trade in the oscars and get irredescent sharks, weather and coolie loaches, and some catfish.
The crabs and crayfish were in my 44 gallon. Over time the crabs died. They were old I think. The crayfish now lives in the 20 long. I am going to set up the 44 gallon for brackish soon. I first have to find out what type of filter and substrate I need.

My god. It must be a fulltime job maintaining the aquarium!!!!
