That Fish Blog – Aquarium Advice and Information

Hello again everyone! Craig here again, and in my last blog I talked about some of the biggest of the freshwater fish to be kept in home aquariums. In this blog, I will go over some of the big saltwater fish found in the hobby. Without a doubt, there are very large fish that call the sea their home. Some of these mammoth fish are being kept by hobbyists. With all the challenges of keeping a marine tank in tip-top condition, adding a giant fish to the mix can present dedicated fish keepers some challenges.

Large fish can be intimidating not only for their size, but their ferocious looks, too. Moray Eels are certainly some of the most intimidating. Their snake-like bodies and gaping mouths often cause people to get squeamish. One species, Gymnothorax favagineus, the Honeycomb Moray, is one of the most beautiful. Also known as the Tessellated Moray, this is one impressive fish. Able to reach a size of over 6 feet in length in the wild, this is definitely a giant. Boasting a beautiful white body with black splotches, there are few morays that are as attractive. In some individuals the dorsal takes on a yellow hue.  Read More »

Within the aquarium hobby there are many niches. There are reef geeks and coral collectors, catfish aficionados and people that think that guppies are the best thing ever. There are also those in the hobby that will give anything, and pay any price, to keep the biggest and baddest fish possible. Everyone loves an impressive fish that screams “Look at me!” But how realistic is it for the casual aquarist to keep a big fish? Well, that depends on the fish really.  Let’s take a look at some of the more commonly kept aquarium giants. Read More »

Everyone has that one fish that started it all for them. Most aquarists can remember that one species of fish that got them hooked into this hobby. Maybe it was an Oscar that would beg for food like a dog, a pair of black convicts that would spawn like rabbits every few weeks, or maybe those beautiful fancy tailed guppies got you interested in keeping fish. For me, it was the Pearl Gourami. I can still recall seeing that first adult trio of Pearl Gouramis in a fully planted aquarium. I was amazed at how the male almost glowed when he was around the two females. Read More »

Owning a reef tank is a really rewarding hobby, but it can be challenging at times.  Besides keeping the water chemistry in good condition, there are other problems that can harm the coral and cause damage to your reef. There are many different corals and therefore many different pests that may prey on each species.  A lot of invertebrates in the ocean evolve to only eat a specific food item. This is the case for many of the nudibranchs, and many have adapted to be coral eating nudibranchs.  As a reef keeper there is a possibility that you will encounter Zooanthid eating nudibranchs, aptasia eating nudibranchs, soft coral eating nudibranchs, and hard coral eating nudibranchs to name a few. Today, I want to discuss is the soft coral eating type.  Read More »

Hello everyone, Craig here again. If you have read some of my previous blogs, you know that I am a catfish fan. If it is weird and ugly, has whiskers and swims, I probably think it is one of the coolest things ever! Last night I was watching River Monsters. One of the trivia questions posed during a commercial break asked the show’s host what fish had given him his most painful injury. Though answer choices ranged included piranhas, catfish and others, and it was indeed the catfish that host Jeremy Wade said had given him his most painful injury. Apparently, one of the 8 inch barbs from an African species of catfish had run through the length of his finger. Having been stuck by my fair share of catfish (though much smaller species), I can say that a catfish spine can be an extremely painful injury with long-lasting effects. Read More »
