Stress, A Potential Killer

With a successful marine aquarium, be it a fish only or reef system, the term ‘stress’ seems inappropriate. Beautiful fish gliding about, corals swaying in the currents, shrimps on their eternal quest for another morsel to eat. Aquarists sit and watch the living picture with a sense just the opposite to stress.

In the human world stress is well known. The so-called rat-race, people getting to work, then being overworked, then sitting in traffic jams on the way home again – and all the rest. Stress is recognised medically as a problem, and it can lead to complications if not dealt with.

The marine aquarium world is not different. There is a difference in cause, but the affect on the afflicted can be no less catastrophic.

On the wild reef natural stress is part of the daily routine. Fish can be chased by and perhaps escape from predators. Predators create the need to hide for security. In breeding periods there is competition. There may be brushes with disease. Life on the wild reef can generally cope.

Fish Euthanasia

Not a pleasant subject, so why write about it? Only because many years ago I was faced with the problem of a very sick and obviously suffering fish and I couldn’t do anything about it, and couldn’t stand to see it go on. At the time those more experienced were unable to suggest the problem, but did advise on how the fish could be relieved of its misery. Thankfully I have never faced such a problem since and fingers crossed never will.

The aquarist who does all the proper things may never need to consider the subject. I feel reasonably certain that the majority of marine aquarists have never had such an awful decision to make.

What To Look For When Considering Purchasing A New Fish

I went down to my local fish shop today as I needed some more salt. I have known the owner for many years now and he knows my saltwater aquarium nearly as well as I do.

I had a good look at the corals and the fish whilst I was there and then settled down with a coffee to have a good chat with the owner.

People cam in and out of the shop – some purchased and some did not.

Good Starter Fish For The Saltwater Aquarium

Once all the research, planning and waiting is complete and the aquarium is full of water and has finally finished cycling you will finally be ready to introduce your first fish.

It is important to ensure that you make the right choice though as there are some fish which are suitable to be added at this stage and there are fish which are not.

The Creation Of A Marine Aquarist

Phase 1.

I had to go down to town today. There’s this pet shop, thought if I have time I’ll pop in for a look when the car’s fixed. As it happened I had loads of time, so had a long look round. It was quite interesting. For sale were a lot of aquariums of many different sizes and shapes. Expensive though, the ones with equipment on. Had a look at the fish too. Wow! The colours and shapes were amazing. A salesman asked if he could help, said I was just looking round. He said the fish were tropical marine fish. He also showed me corals. I never knew these were available at all.

How To Acclimitise New Corals And Fish Correctly

It always amazes me how many people I see or talk to who purchase a marine animal, take it home, open the bag and pour it into their aquarium. I can never understand why some people do not acclimitise their purchases properly, it could be laziness, lack of knowledge, impatience etc but one thing is for certain life is on the line here so it must be done correctly.

The purpose of acclimatisation is simple – the water that the animal is packaged in may have a different temperature, pH and salinity than that of your aquarium. Aquatic life (especially corals and invertebrates) are very sensitive to minor changes in water parameters therefore acclimatisation is a definate requirement for success.
