4 or 5 years ago, I got into quite the hot debate with a store owner in Blue Springs. MO about these fish. He swore they were petricola, and I couldn't convince him that just because he ordered petricola did NOT mean he'd received them and why. He was totally uninterested in any of the facts, and calmly sold 30 of them as something they quite obviously were not.
When I moved to Anchorage, the LFS that I started working at had 3 of them in a tank that wasn't labelled. I never could figure out what they'd been ordered as, or from whom, as he had 9 different unlabelled synos, and just narrowing down and ID'ing some of them was interesting, as only 6 of the id's matched fish he had invoices for. I bought one of them, to go in my mixed Malawi cichlid tank, and sold the other two to a friend with the understanding that I didn't know what they were, or how big they would get for sure.
As mine got about 4 inches, his aggression levels got nasty enough he was a danger to my S. petricola that were about 2/3's grown, and I called the friend and told him to pick him up the next time he was in town. The last I'd heard, they were all still living together in a 55 gallon tank with more cichlids, with only minor skirmishes. He said they were 5 inches or so. They obviously had slowed down on the growth a bit, but I'd assume they're going to mature well over 6 inches, if I had to guess.
I really wish I'd taken some pictures, or had been able to determine at least what they were initially sold to the store as.
