Looks good mate.
Rules are ment to be broken. :-). Just be aware that trouble could flare up at any time but hey, if it's working, leave em be.
Without trying different things, we never learn. My father had so many different cichlids in the one tank, both African and American. Many people still don't believe me until I show pics. Have been accused many times in an aquarium of lying or the best "you must not know your fish, they would never live together". Lol. Not sure if you remember my black orchid spawn, I took dad out when the fry were old enough to JAR. Six or more weeks. :-)
