You did a good job with the pictures! These may be the best of the lot, but keep posting, they are clear and you have a lovely tank.
If you are planning a new tank for the fish you have now, it would only be a short term investment to get a 55 gallon tank. You should consider saving up for a 125 or bigger! The difference in price is huge, but the cost of a 55 setup will only delay that much longer being able to get a bigger tank. Keep your eyes out for a used larger tank, you should be able to find one complete for under $1,000.
