feel free they will all die in 2 months anyway
All of the non tropical fish will die shortly but the tropical or semi tropicals like this burrfish will live forever. This guy I kept over a year, then it got to large and I gave it to a public aquarium. The NY pipefish are almost impossable to keep long term as they usually eat living, tiny grass shrimp and not much else. I have raised and bred the NY seahorses.
The butterflies, angels and big eyes live wellin a reef but the coronetfish and trumpetfish are very hard.
You can sometimes get lookdowns but like lionfish they are rare there.
My favorite thing to collect there are blue claw crabs, which I have for dinner.
Butterflies
Oak Beach seahorses in my reef transfering eggs, these lived a few years as did their offspring.
Some pipefish, blowfish, killies, shrimp, snails and crabs.
And loads of these guys which are not tropical but live forever and get big.
