Neon Gobies. Have tried 2 in diff.tanks at diff. times from seperate stores. And both died in about month.
Kellogi Seahorses (it seems no one has to much sucsess with them)
For some odd reason orange percula and false percula clowns. Have bought 3 over 2 years. All from different retailers and placed them in different tanks(I have 4 salt tanks ranging from 10 to 55 gallon). All died in about 2 months.
I have a black and white clown now. I have had him for 9 months now.
I also had a tomato clown for 2 years. He recently passed away. I just can't keep the orange clowns..lol
