Rate My List!

I have a second hand Trigon 350ltr tank and have ripped out the innards. I've replaced them with an Eheim 2128 external thermo filter which should cope with tanks almost twice what I have. I also have a UV stereliser and plan to heavily plant the tank so am prepared for a heavy bio load. I want to keep my three Hoplo cats which are between 5" and 6" and three pim pictus cats all at 5". I'd really like some bigger fish though and have thought about a senegal bichir, and black ghost knife fish and eventually a pair of severums or festivums.
Is my tank big enough, and are my choice of fish compatible? Are there any largish shoaling tetras that wouldn't fall prey to the bichir or BGK? Your thoughts would be much appreciated.


Cheers,

Wee Al

The list looks ok, no problems that i can see. For tetras try congo tetras.

The sev's might eat some of the plants but other than that it looks good.

Most species of Australian Rainbowfish get to 4+ inches and should be fine with your more aggressive fish. Keep them in a school of 4-6 and they will do fine.

+ there probably two fast & agile for the sengal to catch

i thought BGK grew to 20"?

if theydo, depnding on the width of your tank, then that might need rehoming after a few years.

Ever seen a 20" captive BGK? I'm yet to see or hear of anyone with one over 15".

The tank is a Trigon 350 which it the big cheese wedge shaped tank from Juwel, it goes back about 2 feet and is about 4 feet across the front, should be pleanty big enough.

i actually saw one atleast 15" in length a few weeks back and i did say depending on the width of the tank.

john told me that black knife fish and angle fish are two fish that people constantly try to put in small tanks and they grow a lot slower than they would in the wild, tanks as small as 10 gallons, angelfish can get the size of a dinner plate but usually after they get a certain size they cant grow any more and they get frustrated stop eating and die, most people just assume they have used there life span its very sad indeed, black knifes can get 24 inches in captivity they usually die before they reach that size even in large aqauria also a reason why most of these strange fishes cant be bred because few of them will reach maturity, many fish don’t live to see there full grown size in captivity, and the sad thing about the hobby is that its causing extinction to many small tropical fish in the wild many fish that once flourished in rivers streams and oceans are now only alive in fish farms and tanks.
1 out of a hundred fish caught or bred actually make it to maturity.

Thats not strictly true, while some angel fish species reach large sizes the species commonly kept in the hobby Pterophyllum scalare only has a wild size of around 6 inches maximum (see here for the official fishbase index entry http/filaman.ifm-geomar.de/Summary/speci...iesname=scalare ) Pterophyllum altum grows larger and has much taller fins but is not commonly kept in the hobbt due to their sensative nature and need for soft acidic water.

When fish sizes are given it is from the average size that adult fish are captured at, this however does not mean all the fish of this species will grow to that size. Take a look at fish caught in angling, some lakes/rivers will produce fish of monster sizes while another lake/river will only produce fish of below standard size, water chemistry and food availabilty as well as population density and temperature all play parts as to how large fish will grow. In France the common carp regularly reaches weights in excess of 60lbs while in England a carp of over 40lbs is considered quite exceptional although they are the same species.

The hobby actually has very little impact on fish stocks, more damage is done from enviromental causes such as the damming of rivers, fertilisers from farming and sewage entering the water system and over fishing for commercial food fish.

Do you know of any small tropical fish that have actually become extinct in the wild due to overfishing for the hobby trade? The ones I can think of offhand that are extinct in the wild and commonly seen in the hobby trade have all become extinct due to pollution/depletion of natural habitat. Can you think of any names?

Thanks for your replies guys. Once I have my tank set up I'll post some piccies. I do intend to have a much larger tank eventually. This corner unit is a stop gap until I move to a bigger house which I need anyway for the kids.

Mines got to be pushing 12" but I dont think he'll get any bigger, had him about 6 years.

hmm intersting x_X i find that every one this hobby has such different opinions (ill email this to john to give him something to read )

The redtailed black shark is believed extinct in the wild due to habbitat destruction, the fish keeping hobby is the only reason the species still exists at all.
