Hey, i have an australian redclaw who seems to be lonely and slightly depressed. At the pet store she was housed with an Orange Dwarf Crayfish (Cambarellus patzcuarensis) I believe, as they just have "electric red" written on her tank but she has been there now several months and hasnt grown. She is also starting to look lonely and depressed. I have my Sheila in a clear rubbermaid type contatiner with a cave, heater and pump. I have used this as a pond before and have been calling it an indoor pond since Sheila moved. When full it is 30 gallons. I normally keep it around 20 gallons to prevent escapes. So would it be safe to put these two species together? Like I said the store had these two together previously but it has been several months since they lived together. Neither were injured in the store and I have enough things to make many caves and hiding places to recreate territory for them. They floor space would be about 3ft by 2ft. If i do get the other crayfish and they get along etc is there a possibility of the two species breeding? Sheila is definitely a girl, I haven't examined the Orange Dwarf to know what its gender is. Thoughts PLEASE!
