3- Clown Loaches
1- Firemouth Cichlid
1- Electric Blue Cichlid

I dont know much about cichlids, byt clown loaches should really be in larger groups, they are very, very social. 6 is really aminimum. they tend to grow slow, but they grow to 12 inches eventually. And you would need to plan for that future.

No you should be fine I would just recommend watching the cichlids with the clown loaches cichlids are generally very aggressive good luck.

That is great, you can have even more fish if you like. That is a good setup. Be sure to take care of your fish well.

life is good

What are you calling an "electric blue"? Are you referring to a JD or an African Cichlid? The African cichlid would want very opposite conditions form the other fish you have listed and is not a good choice for that tank. An electric blue JD would be fine. Size wise, you are OK in either case.

The loaches should be good for a very long time, if not forever. They do get OVER a foot long, reaching as high as about a foot an a half, but it takes many many years to obtain that size. A 4 foot long tank is the bare minimum for an adult and the 75 gallon meets that minimum. With the room front to back of 18 inches, it should work for life but be cramped in their later adult years.

The clown loach can live easily over 50 years. (My mother-in-law had hers for 25 years before she sold all her fish. At that age it was about a foot long but still growing a little every year! It was rehomed to a 500 gallon.) Since they do live so long, they tend to grow a bit slower, and after even 5-8 years expect yours to still be under 10 inches long.

The loaches like to school as juveniles but tend to get more solitary as they age. Three is a wonderful stocking choice and will give the juveniles the social structure they crave while allowing room for the adults size and social behavior as they age. You will see some more interesting and even comical behavior from your loaches if you did add two more, though, but it isn't absolutely necessary.

So, given the "electric blue" is not an african lake cichlid, you should be good to go.
