OP can get angry with me if they’d like but I’m just going to say it! Why wouldn’t you take a little time and get educated on the animals you are discussing? It’s brutal on us older keepers when we have to answer topics like this! It’s worrisome for the animals and disappointing ethically! I spend WEEKS reading-viewing 1000s of articles / videos on ANY ANIMAL I obtain. Why don’t you? I want to say... what the he*# are you thinking ? 5 gallon tank and a 100$ budget? If you cared a damn lick about the animal, you’d shave off 20$ for a larger cracked aquarium and talk to a breeder. Most would cut 20$ off an animal especially if they knew you were going to put in it a JAR,.
What about vitamins, calcium, proper lighting..
