Hi everyone! I have a couple questions. Thank you in advance for any guidance. 
My Mom has an established (for 5 years now) 35 gallon tank. It's been housing a goldfish for the last few years. But today he has died. :l I have 4 black widow tetras, and 2 zebra danios currently in a 14 gallon tank. I've had the 6 of them for two years as of next month.
I'd like to move them to her tank. Is there anything I should do before moving them? We're going to give it a good cleaning before moving them. But is there anything we should do or know? Right now the temperature in her tank is the same as mine (since I don't have a heater currently on). We are planning to get 1 or 2 more tetras to make them feel more secure. Should we get more zebra danios too? Also can I school the black widow tetras with other tetras or no?
Also, if anyone knows of some tank mates that'd work out well with them, I'm all ears. I'm going to research myself after I post this. I should mention that we have soft water, so that's always an important choosing factor for me.
