Would this work?

[Yo-Yo]

Someone just gave me a 20 gallon long that's been cycling for 25 years. I currently have a percula and a three stripe damsel I want to get a coral beauty a Javanese damsel and a stars and stripes puffer. Do any of you think there'd be an issue there?

Hello, welcome the the forum! You may be able to add the Damsel and the angel, I have never heard of that puffer before, but I thought puffers needed more than 20 gallons of swimming room (unless it is a super small puffer or something lol). Just be careful if you add the damsel because your current damsel may be aggressive towards it. Good luck!

Actually the place I get them just got a porcupine puffer so what do you think about that instead of the stars and stripes

I would not put a puffer in a 20 ... ..The tank is just big enough for the dwarf angel,,but just barely ..They get 5+ inches and may not be able to stay in there for life..

Ok thx for the advice

Your tank is way too small for a stars & stripped puffer and a porcupine puffer. Both will around 2-3 foot long. Tank size should be in the 100s or 200s gallon. Here is a pic of a massive stars & stripped puffer taken last week during my road trip:

They dont get 2-3 feet. The porcs will get 1' and stars and stripes a little bigger. Still 100+ gals tho. I personally dont think thatl work for a dwarf angel. MAYBE only and african dwarf flameback.

Actually a coral beauty has been in this aquarium before.

it's not a good tank for even a pigmy angel IMO. what happened to the coral beauty that was in the aquarium before? generally, fish live 10-15 years.

Wait am I the only person that noticed that the tank has been cycling FOR 25 YEARS?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?! Is that a typo?!?!?!?!?

 

[mr_X]

i assumed he meant it's been running for 2.5 years.

 

[huma-huma]

haha talk about a long cycle, def wouldnt do a puffer in a 20 with other fish, unless it was a pea puffer...

 

[Yo-Yo]

Ya it's been cycling for 25 years not a typo

 

[Strawman]

Are you sure your using the term cycling right? Cause that means your ammonia and/or nitrates and/or nitrates are all high and not at zero. Most fish would die in a month or shorter under these conditions. Converted Millie's are the only fish I can think that might make it and those odds are still slim. A twenty five year cycle might make sense for a large sea. But that's still long. Restart the entire system would be my suggestion

 

[Yo-Yo]

It's been running for 25 years then

 

[Strawman]

So the tank has been up for twenty five years. But it had cycled and is no longer cycling.
