Removing the gravel probably removed a lot of bacteria that kept the water safe for the fish, while at the same time, stirring up a lot of "nasties" into circulation.   Many would say (especially in europe) that two fancy goldfish require at least 140 litres of water to live in.   It is hard to...

I would suggest a ~95% water change pronto in the goby's current tank   One of the worse things you can do is put fish into a smaller tank, when the tank and its filter is not cycled. There is less volume to dilute the ammonia and nitrite, so levels will reach deadly toxic levels quicker.  ...

How many of each of these midwater fish are in this ~70x65x51cm tank?   Which plec species did you have?   What food were you giving this catfish?   Were you regularly seeing this catfish actively eat the food you added?

Ctenopoma acutirostre are very easy to feed dried foods, my four year old group eat Tetra Prima; Doromin; Cichlid XL; New Era Tropical Pellet; New Era Plec Pellet; Hikari Cichlid Gold.   Feeder fish, besides the whole ethical debate (it is illegal to use them in the UK), are a major risk for...

I've seen the anti-social personality of Redline Torpedo Barbs first-hand, I started with 3 and there was a dramatic change when I added another 3 to their QT a few days later.   Moving them between tanks is a loaded game of "Russian roulette," they are unbelievably sensitive to water chemistry...

How long is this hex tank?   Congo Tetras (Phenacogrammus interrptus) are moderate sized, semi-active fish that need at least 120cm of tank length. I have six that youngsters (~3.5-5cm SL) that make good use of a 120x30x37cm tank. They are rather adaptable as far as water hardness goes, upto gH...

10+ of any social species acts more natural and looks great, my biggest group is 25 midwater; diurnal; schooling catfish (Pareutropius mandevillei).

The tank dimensions could work, you could even add a small group (6) of small, upper water "dithers" that are comfortable in the conditions Chaetostoma spp. need (10-20x real turnover with plenty of surface movement, 20-23C). A few options that spring to mind are Bloodfin Tetras (Aphyocharax...

Are you aware that some rainbows including Pseudomugil gertrudae are not "tropical" fish? During the year, their natural waters are recorded to change from 12-34C.   http://rainbowfish.angfaqld.org.au/Gertrud.htm (site is great reference for rainbows)   Such fish can be kept in a tank without a...

A group of 10+, in a 5-foot tank that changes temperature through the seasons (~15C winter season through to ~25C summer season; spring/autumn ~20C) and lots of water movement for high oxygen levels in a sight to behold.   A very misunderstood fish in the hobby, they are not "tropical" fish.

25% monthly water changes is rather low, I do ~50% weekly changes on my five active tanks, including my African Congo/oddball 6-footer.   Even though you have a nitrate reading of 100mg/l, it could be higher, the test reagents fall out of solution and give false lower results. Shaking/banging...

In my experience, detectable traces of nitrite tend to be more lethal in the short term than ammonia. Nitrite messes with the ability of fish to supply their body with oxygen, a classic sign of nitrite issues is when fish are gasping at the surface (which can also be a sign of simply low oxygen...

Hopefully you are letting that tank temp cool during a winter period, Buenos Aires Tetras are not "tropical" fish, they have evolved in a region where the temp drops to ~16C.   Taking the seasonal/temperate conditions above into consideration, temperate Corydoras should be chosen, such as...

What are the ammonia and nitrite readings now? How warm is the water? What pH is the water? Have you still got the old bio cubes?   On the face of it, this sounds like you have removed a lot of the beneficial bacteria and you are now "fish in cycling."   If you have been doing frequent (weekly)...

I really do hope you have mistyped in this post between "degrees" of hardness and milligrams per litre! ;)
