New here!

Hi all, relatively new to fish keeping here! Got two small tanks at the moment, a 54 litre and a 14 litre.
Started off with fish this time last year when I was given a present of two small goldfish and a 6-litre bowl:unsure:
Then a while later I inherited the 54-litre tank and also some fish for it. When I got this I did some research on the web and found out how fish should be kept, water chemistry etc.

Anyway, the 54L tank was overstocked so I got rid of some of the fish (2angel fish among other things!). Around this time I saw the 14L tank in Aldi/Lidl so I went ahead and got this to home the goldfish.
Currently in the 54L tank I have:
3 Black Neon Tetra
2 Platys (1M 1F)
2 Madagascan Rainbow Fish
1 Pleco
The Pleco is getting too big for the tank, I have a home that he will be going to in the New Year and I'm looking to replace him with a Siamese Algae Eater.
Also probably going to rehome the two rainbow's as I've read they like a large tank with lots of swimming space.
Anyone any thoughts of what else I could add or do I have too many fish as it is? I don't like the platy's their pretty boring and I hear they breed like wildfire!

Sadly one of the goldfish died last week. He was the smaller of the two, about 1.5\" long. So at the moment I have the larger goldfish (3\") in the 14L tank on his own. Is this tank big enough for him? Is it alright to keep him on his own or should I get him a mate? 2 Goldfish is probably too many for that tank so is there anything else that would be suitable? Is there anything (shrimp, snails etc) I can add to it? Anything that would help get-rid of algae?

I've added pics of the tank. They're not the best pics and the water appears a little cloudy in both, this is as I took them just after turning back on the filters after a water change! There is also a bit of an algae build-up at the base and corners of the bigger tank, I've just made the gravel a bit shallower around the edges so hopefully the plec will get at it tonight.
Thanks for any help/advice guys!

Hi alcers this is just my view please do not take this the wrong way.I would first take the mains block off the top of the tank if the fish tries to make a leap of faith he could burn your house down or at the least blow a fuse or kill himself.The large tank is grand i would be a bit worried of the algae growing only in the joints is it an old tank?.The small tank i think is to small for your goldfish i myself would only keep a a few danos or guppys or tetras in there.There is alot more people with more experience than me on the forum this is just my 2 cents.And welcome to the forum

Hi Pierce,
thanks for the reply. I think the plug block is safe enough on the lid as my fish are small but I'm going to mount it on the wall over the weekend anyway!
I made a mistake in my other post, I have two guppys (1M 1F) in the big(ger)tank, not platys.
The algae grows everywhere in the main tank, just I can't scrape it off at the joints, is it something to worry about or does it only affect appearance?
Any thoughts on what would be a good addition to the 54L tank, something colorful?
I might get a bigger tank in the new year, put the goldfish in the 54L tank and the guppys in the 14L one. Would there be much work involved in changing the tank from being for tropical fish to one for goldfish?
Anyone else have any thoughts?
Thanks

if you are moving the guppys get at least 2 more females cause the male will hunt after her to death. I would also recommend plants they add colour and help keep the water clean. do you have a test kit? if not get one it helps a lot. you seem to be doing well otherwise but i am also not the most experienced by any means so i may be corrected in what iv said.

UPDATE - Upgraded!
Gone and upgraded my tank to a Vision 180:

Going to put the two Goldfish into the 54L and try and find a Betta for the 14L.
Any thoughts on what to add to the Vision 180, it's a bit bare at the moment, willing to give plants a go!
Would love two Angelfish and a red-tail black shark, is the tank big enough?
Also when I put the goldfish into the 54L I will have a heater in it, should I just set it to it's lowest or what temperature do they prefer? They're in an unheated tank atm but it's very small. I'm going to use the same filter in the 54l that I was using with tropicals, will the same bacteria work or will it die by not being at such a warm temperature?
Thanks

Nice tank i have one the same.I think angels will look well in it plus your shark you have loads of room i think your safe enough to but in bala sharks or silver dollors also.You don,t need a heater for goldfish as they can live in water just below frezzing but if you have one spare it,s good to keep the water at a steady tempeture.So the lowest setting would be fine.I don,t think you will have any bother using the same filter using the same filter.Mine is an open top tank does yours have a hood with lighting? there are plants that need alot of lighting ao if you let us know what lighting you have maybe someone with more experience with plants could help you.imo i think you can get some nice fake plants now.Keep us posted on how your getting on and congrats on the new tank
