Tried to edit, but ran out of time right before I posted.
Ok, some photos. Unfortunately I've gone and lost the earlier ones of my smaller Male(?) Severum, but that's fine, he's a much more docile fish. My larger female is most definitely the dominant fish of the tank, one of those glass banging Severum you occasionally hear about.
Little bit of background. Was in a well maintained 42Gal 3 foot for a few months, is now in a 140Gal that is understocked, 30% W/C every week or sometimes every 5 or so days. Nitrates never hit over 10, let alone 20ppm.
Fed twice a day, with a mix of Hikari Cichlid Gold, Hikari Staple, Orca High Protein pellets, but not these so much anymore. Vegetable meal for lunch, usually skinned Peas but often mixed up with diced Cucumber and Zuccini. Occasionally crush up an Hikari Algae Wafer in the Mortar and Pestle and feed that too.
First day of purchase, November 26, 2007. I can't say exactly what size she was then, I'd estimate 2".
Forgive the crappy photos, tanks a bit dirt as I did a water change earlier, today, Friday 29th February.
Current size would be around 4.5-5" I'd say. Very bulky but not fat, too.
As for my smaller Male(?).
February 4th after being introduced to the new tank.
Bit banged up from the larger Severum, but he gets his fair share of food. Today, February 29, 2008. He would have been perhaps 2.2" when introduced in early January, and would now be closer to 3.5".
All of these measurements are guesstimates. Hope you get the general picture.
