Thank you. Not sure on the blotches on top if it is a sveni. They are in a bottom tank and hide except to attack the pellets and mysis as if they are alive. Going to try for seperate and better pics of both. The second one doesn't have blotches as visible as this one but don't know if it is a dominance issue , sex or different species. Hopefully figure it out with a little help.... Thinking 2 different fish but will have more pics in a few days. Anyone else have trouble getting on the site last week? Wonderring if it is my browser setting or the site doing maintenance. Thanks again.
