Welcome to TFF.
As this was your first post, and my first response to you, I am sorry it will be a bit negative. You have some issues already with fish.
First, is this a new tank, with fairly newly acquired fish? [I won't get into cycling, just mention it.] The clown loach needs a group of five minimum, or more, as it is a highly social fish and will be severely stressed without companions of its own species. But it also grows to 8 to 12 inches, and this tank is insufficient space for even one much less five. Can you return it? I hope so, as this is a problem.
The two angelfish could be another problem, depending upon their gender and whether or not they decide to bond or oppose one another. This is also as shoaling fish that lives in groups, and forms hierarchies. Two fish will only work long-term if they are male/female and decide they like each other enough to form a bond. But regardless of that, you do not want to add a third, that will result in a dead angelfish before many weeks have passed, almost guaranteed.
Next question is water parameters. Some fish have very specific needs when it comes to water hardness. Do you know the GH (general or total hardness) of your source water? And KH (Alkanity or carbonate hardness) and pH while you're at it. The website of your municipal water authority might have this data. Until we know this I cannot offer much more. Except that you have too many blue rams, though if you lucked out and all are female except one, it might work. I personally do not advise acquiring the "balloon" type of this or any species; this is not a natural condition and the fish will have internal issues because of this frankly cruel practice, and the only way to end it is by not buying balloon fish.
