| Raising Clownfish Marine Fish - Clownfish  Family: PomacentridaeThe spawning of clownfish nearly always takes place in the late afternoon and is a delightful scene to observe. A common precursor to this and a good indication of imminent egg laying is the ritual cleaning of the chosen spawning site. Both male and female clean the site vigorously with their mouths until they are both satisfied that the surface will be suitable. Meanwhile, the egg laying tube, or ovipositor will have become clearly visible in the female, while the male's fertilisation tube may only just be obvious. |
| Captivating Cardinals Marine Fish - Cardinals  Whilst the coloration and behaviour of this family of fishes could never be regarded as wildly over-the-top in the same as, say, clownfish, they nevertheless have a subdued charm that appeals to the marine fishkeeper. In addition, these are some of the easiest fish to maintain and the newcomer would do well to put the mane of cardinalfish down for consideration if a community of smallish fish is to be the objective. |
| The Micro Shrimp Tank Marine Invertebrates - Shrimps  Most of my regular readers will already be aware that, on the whole, I do not condone small marine tanks; that is, tanks with a nett volume of less than 20 gallons (91 litres). They are usually very unstable as far as water parameters are concerned and subsequently exert considerable stress on fish and/or invertebrates. They are also extremely restricting for livestock and consequently prone to overstocking, especially where fish are involved. Having said that, there is a way that the marine enthusiast can set-up a 'micro' marine aquarium housing only shrimps! Over recent years, I have been experimenting with 3-5 gallon marine aquaria containing various species of tropical and temperate shrimp and crabs. I am pleased to report that all tanks were successful and no livestock was lost. |
| Livestock Marine Fish - General Marine Articles  Marinists who follow the hobby closely may have recently noticed that there has been a marked swing away from interest in livestock (fish, invertebrates & algae) to a blanket coverage of hardware, almost to the point of obsession! There are often bitter disputes about who ‘invented’ what, when and how (as if it REALLY matters!). Filtration systems come in and out of favour like so many different clothes! It gets all very confusing and extremely expensive for those people prepared to follow ‘aquatic fashion’. |
Big Fish for The Marine Aquarium!
One type of marine aquarium never fails to create a stir, the fish-only tank containing BIG fish! The sight of large slices of brightly coloured piscine flesh cruising around an equally spacious aquarium is enough to make anyone's heart beat a little quicker.
