My next investment is going to be a filter. I’ve done some research on how big angelfish get and what size tank they need. The temp stays at 75 to 80.Cool!
Do you mind if I give you some pointers?
The Angel fish are going to grow big, and they are very territorial. They need huge tanks to thrive.
The white fish looks like a skirt tetra. They do best in groups of at least 6, and they are known to be terrible fin nippers. He'll nip the Angel fish's fins.
The fish sitting on the substrate is some kind of albino cory. They also do best in groups of at least 6.
The tank needs a filter. It will add oxygen to the water, keep the water cleaner, and it gives the beneficial bacteria a place to grow.
There's no heater, but in Florida that might be okay. I don't know how low your temps get there.
Did you cycle the tank before adding fish?
I do not own a tetra of any kind, I’m not sure which one you’re talking about.
