The colombian shark looks and acts exactly like a salmon tailed catfish, found natively in Australia. Thats leads me to believe that they are the same. If that is the case(which I really think it is), then it wont ever need salt or brackish water, but can certainly handle it just fine(the largest variety of them is sometimes found on offshore reefs!). I have had personal experience keeping them in tanks, and they are very predatory, esp when bigger. There are several distinct varieties of them, some growing no bigger than 40cm, some growing over 4feet in length(I once caught one 4ft long while fishing in the Pioneer River, in a deep section). All the ones that I have kept have been wild caught, and upon them getting too big, were released back into the same river that they came from. I think that the 'colombian shark' is actually a salmon or fork tailed catfish, native to Australia, cheers

The red is prettier but if that means it is dying, I am ok with that too.

I found a snail. I don't know how it survived after all that I did. I've only ever seen one other snail (possibly the same one). If there are more I am ok with that if it doesn't destroy leaves.. Will they eat this type of algae? It was about as round as a Bic pen tube and a little quick moving. I saw it on the front glass.

generalized, ... the only snails i've heard of that are acceptable for algae control are brackish. (nerite snails)

i have not heard of any truly freshwater snails that do much about algae at all.


i also notice many people giving snails a bad rap for eating leaves, ...

i've seen nutrient deficiencies that people blame snails for

snails will eat dead/decomposing matter, ... could be dead fish, could be dead plants, ... but they don't care too much about the live stuff at all. they may munch on the dead stuff at the edges of those holes you're seeing.

otherwise consider nutrient deficiencies or fish before thinking your snails are eating your plants.

sadly this includes algae, ... the nerite snail being the only exception i have heard of for algae control

I am totally ok with snails. I don't have any holes in leaves but it's good to know they will eat dead/decomposing stuff. This should include uneaten food on the bottom? Like I said, they're ok as long as they're not destroying plants.

Ramshorns are epic for algae cleaning, malaysian trumpet snails aren't bad algae cleaning that is. The problem with staghorn algae is it's tough stuff, so there aren't a lot of species of snails, or fish for that matter, who will eat it. Though mollies tend to like it ok, they wont clear it up. The other problem is...they will breeeeeeeeed. Fast and a lot.

Nerites though, nerites only breed in brackish settings. They live in freshwater, but only lay hatchable eggs in brackish water. However, you have some pretty big, and aggressive fish in there who will likely not allow them to feed as they should nerites can hide in their shells for weeks, months even, if pestered and eventually will starve if the fish don't kill them first. Angels, and quite probably the cat shark, will likely kill them, or try to...but they may leave adults alone. I don't know. o-o

Turning on the Aquarium lamp in the morning is MY cup of coffee.

Continue dosing daily the FlorinMulti at 6 drops per day and the FlorinAxis at 12 drops per day. This is after initial dosing of 5ml after a 50% water change. My hornwort is growing very well and I notice some nice growth on the anacharis that has survived. Am I the only one who has not had this plant survive? Now wondering if I should start with some Excel. Should I use the FlorinAxis and Excel together? Do I have to dose Excel every day forever or is there a weekly dose? Can I discontinue use of Excel? If I use say a whole bottle what happens to plants is I stop using it and start using FlorinAxis again? I keep pulling this algae out and I feel like I am fighting a losing battle and would like to try Excel for the algae controlling properties.

Currently readings are
Ammonia 0
NitrIte 0
NitrAte 20

Will be doing a small water change today.

there isn't enough information available (for my liking) about algae

what it does seem like, ... pulling it out, breaking it, cutting it, ... any small part that you miss removing is left to float in the water column, ... when it settles, where it settles, ... it's free to attach and continue growing, giving you a new place that algae is present in your tank

i do not know if when you are pruning your algae you are doing this during a water change to siphon all algae cuttings out of the tank with the water being removed. to have it sucked down the hose and ensure it does not attach in the tank.


i found staghorn algae to be rather pretty, ... in small amounts. even more so when algae (any kind of algae) attaches to snail shells, i changed my mind when it became excessive, ... like yourself i couldn't stand it at that point.

what i searched for was critters to deal with it, ... concerning staghorn algae, findings were not very conclusive, green algae is much more reliable to find critters that love to eat the stuff.
