Alright I’ll give it a try. Note, I have only kept males. It’s already been said they like NOT to eat, (3 to 5 months is nothing) so that’s one. Around 700 maybe 800 grams you find a lot of sperm plugs, there’s two. They love to mess their habitats as soon as you put in fresh water, number one and number two = three, get it , sorry. Once they get eating they can be machines, fart machines that is, no. 4. And husbandry is important and with that there are more ways then one to skin a cat. Fifth!
