I have a very calm and fat super hypo tangerine Carrot tail morph. I love him so much and eats everything! Who has these guys?! They are great for beginners and experts!

I've had this tank running for 5 years and the stock changed a lot with it. Its 37 gallons and densely planted with live plants. I have a filter rated for 90-100 gallons running on it currently.

This is the current stock list:

1 Koi angelfish

14 Black Neon Tetras

10 Peppered Corydoras

Is that to many fish or no? I have a decent shoal of tetras and corys. The angel is the only large fish in this tank. The tetras range from 1.5-2" and to large to eaten. The size of the angel is about 3-4" tall and he well max out at 6-7". The corys 2.5" max.

I had this angelfish for 4 years, with black neons with no issues. But I been reading that Angelfish shouldn't be kept with Black Neon Tetras and that Bolivian Rams can't be with them as well. The rams are new to the tank. The gourami I had for 5 months now, but I haven't had issues with her yet. But are these compatible with each other? I love these fish and I don't want to move the older fish.

Other fish in the tank: (just if you want to know)

Albino Ruby Shark (I know they can get nasty, but it only chases my guppy)

guppies

cories

kuhli loaches

pleco (clown plec)

2 other small catfish

Also the tank is 37 gallons.

I have 5 Black Neon's, but 3 are close to 6 years old, how long do they normally live for? I also have a 5 year old Angelfish, how long do they normally live for? I had these fish for quite awhile and they are in the same tank. The neons are showing signs of old age, but the angel isn't, expect her fins dying at parts and regrowing.
