I "had"(as of a month ago) a yuma dominant nano tank, plus i guess i can say i do fairly well with keeping yumas. Ive kept my current alive for more then 3 years, including the beautifully colored ones. Now for what ive experienced, never buy a yuma that is detached or damaged, that was just imported, or even looks the slightest bit of stressed. No matter what you do or how good your water quality is, theyll usually catch an infection due to those reasons. I lost 6 of my prized yumas just recently, that ive never had 1 problem with other then growing to the size of carpet nems. All it took was 1 night, i forgot to set my home temp, and my tank dropped just 1° colder then its usual fluctuations. Next morning i woke up, and every single yuma i had- dropped 1-2 babys each. At the time i was happy, little did i know they caught a bacteria infection and half of them died withen a week. Water quality was perfect, babys survived, but thats all it took to kill them. I cant even begin to explain how bad i neglected the tank those 3 years of keeping them, i had to have done everything to kill them (on accident mostly lazy) but never once had temperature problems. I never put a finger on anything in this hobby, because with some situations you just dont know. But the only thing differently that happened that night was the temp swing, so maybe this can attribute to a care guide on yuma keeping
