How does this look for my aquarium?

You're talking about 23 fish for about a 40 gallon aquarium after the inclusion of rocks, gravel and other accoutrements. That's a lot of fish.

It is customary to keep 1 to 2 inches of fish length per gallon of fresh water, or 1 inch of fish length per gallon of salt water in a marine aquarium. I have personally been successful in stretching that limit with much older established aquaria, but I don't recommend it for the average aquarist.

You're probably coming very close to the limit and I recommend adding them only a few at a time and then waiting 2-3 weeks between additions, or else you could stress your aquarium fairly quickly, resulting in a bunch of dead fish. Be sure to keep a close eye on the nitrogen cycle (ammonia, nitrite and nitrate) during that time.

That is alot for your tank size.. Remember the rule of 1-2 inches of fish per gallon, and this is there adult size. I try to stay closer to 1 inch a gallon myself, you'll find you have alot less problems, especially in a new tank. The upside down catfish and kribensis can both be 4 inches as adults.. so those 5 fish is 20inches already nearing a good tank load. Im not really sure how big the blue rainbow fish get. keep in mind that anyone that tells you a fish will stay small in a small tank has no clue what there talking about.

Whatever you decide to add, remember to add no more then 3-5 fish at a time, I would start with the 4 tiger barbs and give them a good 2 weeks before adding the next batch. a beautiful tank takes time, if you rush it, you'll run into problems. And good for you for cycling your tank and taking the time to do some research before dumping a bag full of random fish in to your new tank. Good luck :)

captivating! you have my flavor. It seems all organic, which i individually love aobut fish tanks! If i've got been you, i could upload an extremely small piece of malasian driftwood that hides a pair of million/4 to a million/3 at the back of the rock. the it may be beast! additionally, what fish are in there? seems to me like a angel and a platy?in step with danger additionally a guppy? It there's a angel, it is going to wish a larger tank. yet aweosme job!

the only thing i see it that the kribs could become terotorail

the only thing i can see is that the kribs could become territorial.
