TT, I found your defense to be completely tangent to the issue that was brought up. You never did serve your suspension, you protested it the entire time.
In the future, all suspensions must be served in a timely manner. And if you wish to appeal, it must be formally stated, along with a proper rationale.
Unfortunately, you are applying the conjunction rule improperly - as the rule you cited is for a list, whereas the comma you had an issue with was separating two independent clauses. Those are different rules, so you stand guilty as charged of incorrectly correcting a mod's punctuation, which is a serious offense here in this thread. You are given two pages probation, during this time you are prohibited from addressing any and all grammar or punctuation, whether it is correct or incorrect.
Large ones might be a problem with mating kribs too. Personally, I wouldn't do it. If you were to do it, I'd say that Brochis splendens (Emerald "Cory") would be a better choice as they can grow over 3 inches.
