Also, I would worry about the flow rate. External cannisters don't really deal with head as they are taking water from the same height as they are returning it and thus hitting a near equilibrium. I do not think the same flow rate would be achieved when pumping from a lower area to a higher...

I have 3 lists really: Freshwater fish I own: 1) Chalceus (either Chalceus macrolepidotus or C. erythrurus) Like a 10" tetra with needle teeth 2) Bala sharks - Great to watch them shoaling once they get larger (8"+) 3)Rainbow snakehead (Channa bleheri) - Great little fish with plenty of...

I can't take any real credit, a friend did all the legwork, I just re-post his efforts.

Plenty of people skip ferts. On another forum two UK guys stopped using dechlor and found the fish were fin even 6 months later and even looked brighter. I know of someone else I chat to who stopped using dechlor on her tanks about 6 months ago and has had no problems. Chlorine gasses out of...

Cannisters are ok, but the best will always be a sump system unless you are after a FW planted aquarium. The sump increases the volume (Adding stability) and with a wet dry can handle the messiest of predatory fish (FW or SW). In SW you can then add on a refugium and grow macroalgae or lay...

Good pic. As posted above, electric eels are from the South American Knife family, and thus are related to Black Ghost Knives.

Scorps and lions both occur in the same family (Scorpaenidae) but just belong to different subfamilies (Scorpaeninae and Pteroinae). Stonefish are, again, just another subfamily (Synanceinae) within Scorpaenidae. Most families are very similar, look at all the catfish in the Doradidae family...

I have asked elsewhere and it is almost definitely Pteroidichthys amboinensis. The supraorbital filaments (eye tentacles) are the main giveaway that stop it being Inimicus spp. Apparently they are not great captive pets with a number not living past a year. The main problem for me right now...

Well, I saw this guy at the weekend and decided last night that despite my initial thoughts, I do have room for him somewhere, so I sent nina out to pick him up. The shop had him labelled up as a "Pop-Eye Sea Goblin" but in a surprise turn of events also had a scientific name for him: Inimicus...

Unless you count gymnothorax polyuranodon the true freshwater moray eel :wink:

A quick wiki search produces this response which agrees with the reference books I have at home: As an aside, the electric eel is not a true eel, but a member of the knifefish family. If you are ever lucky enough to see one swimming you will see it moves in the same manner as other knives...

If you look at this information by Neale Monks (an author and editor on brackish aquaria and fish) you will find there are a number of completely freshwater species of sole, including: Some of Cynoglossus spp Brachirus harmandi Brachirus pan Synaptura salinarum However, identifying to a...

A real eel (Order Anguilliformes) is still a fish. Using the taxonomic groupings after Nelson [1994] and Compagno [1991] they are in Subdivision Elopomorpha (with the tarpons, bonefish and gulpers) under Division Teleostei (bony fishes) which makes them a bony fish, closer related to most fish...

Flounders are pretty heavily nocturnal feeders and do not do well at competing with other bottom feeders for food (such as plecs, corys or other catfish). There are some that live their whole lives in FW, but I seem to recall the most common one seen in American lfs is the Hogchoker Sole which...

It's not so much that the bubbles are tiny or have a high surface area, but they just aren't in the water long enough to allow any significant or appreciable amount of gas to dissolve from the bubble to the water. While they will increase surface agitation upon reaching the water's surface, IME...
