The slate is from the Slate Islands of the Inner Hebrides http://www.easdale.org/ - it is definitely slate, but is from the shores of the islands, so perhaps its the unwanted stuff left behind?
I could try harder to find stuff without pyrite (fools gold). Typical - I picked out some perfect pieces for my slate wall and had it all washed and ready... Glad I checked though, as each piece has at least one bit of pyrite on it.
For info - http://en.wikipedia.org/wiki/Slate - states that slate is often used as a decor in freshwater aquariums. Slate will not alter the chemistry of water (except in the slate containing felspar which may leach silicates into the water resulting in excess diatom growth in marine aquaria).
Re: How To Move Your Aquarium When Moving House
I am preparing for moving my fish a ten hour journey.
The new tank is set up at the new house, and I am happy about moving most of the fish up - have heat packs, polystyrene boxes, bags, etc, etc.
But, I have three large catfish (8", 9.5" & 10") with big spines, who I'd rather not put in bags. How would you go about moving them? I have plastic tanks for each, but am not sure if they are the best option? Especially if they are only to be filled a third with water - not much space for them to move around for all that time.
Also, would you be happy moving 6" clown loaches (and their barbels) in bags, or would plastic tanks be best for that too?
Have just bought a lovely new 55 gallon aquarium from Kent Cabinets (go on, look em up!), and now have a Juwel Rio 180 spare to do with as I wish... After thinking long and hard, I'd love to have a Tangy set up.
Questions are... Are they compatible with each other? How many of each would comfortably live in an aquarium of this size? Will my banjo catfish and spotted talking catfish be suitable tankmates (thought they may appreciate the sand)? Would you bother with shoaling top dwellers?
I'd like to set it up with a wall of slates laying randomly on top of one another at the back, creating lots of different sized caves, and nothing in the foreground, so plenty of swimming space.
Does this all seem okay? Appart from a fantastic pair of Kribs, I have never ventured into the world of cichlids, so appreciate any help!
I have three mature catfish - a plec (10"), and two synodontis (9.5" and 8") in my 55 gallon tank. They have always hidden for a portion of the day, but are generally very active. They have now grown out of their hidey holes and are getting a little irate with one another.
They have a horrible plastic tree stump that only one can fit into, with a careful squeeze I have tried creating structures out of rocks and slate, bogwood (~10 pieces), etc - but they seem to want proper dark tunnels.
I have a couple of queries: 1. Would it be harmful to put in a clay pipe/pot which has an unknown glaze? Obviously boiled up beforehand. 2. Has anyone else had this problem and did you find a tasteful solution. 3. Is it necessary for them to have a space of their own, do your cats have this? Is it that my lighting is too harsh for them?
Re: Internal Juwel Filters - Any Good or Add Another / Rip out
I've had a Rio 180 for a few years, and had all sorts of problems with the filter - neons getting trapped between the plastic and the glass and clowns getting stuck in the insides of the machine. Also, the powerhead was useless, the filter was constantly clogged up in a planted set up, the list goes on... I ripped it out and replaced it with my good old trusty Fluval!
