So I got myself a nice 35 Gal tank from my father in law and decided to set myself up a tropical tank .. It's been up and running since feb 12th .. At first I had two aquatic frogs in it, one acf and one adf .. and had two plastic compartments on different sides of the tank that had my bettas in them .. after a couple weeks I added 6 neons and everybody seem'd to be doing great .. The first casualty was the acf , climed into the filter and drowned in there .. took me 2 weeks to find out what happind to it .. Next one of the bettas was acting sickly so we put him back into his bowl he had been in for the past 8 months happily.. poor guy looked on the brink of death and couldn't swim but he's managed to hang in there, still has trouble swimming though, like he gets stuck on the surface... Next one of the tetras starting seeming sickly, faded colour and not schooling so I paniced thinking it was sick and would infect the others so I put it in a small bowl overnight, I then felt bad for it and dumped him back in the next morning, not thinking about temp change and it became paralised right away and died soon after ... next the ADF dissapeared, I looked in the filter and it had got himself in there to, but he was still alive so I managed to save him, and I put some netting over the filter thingy so it won't happin again ... Over the next couple weeks I noticed what looked like white dots on the fish, especialy the betta.. I got some different chemicals, this betta fix stuff, malafex are something like that, and waste removal .. used the malafex for a couple days and didn't notice any change... been useing the waste control on the maitanence dosage once a week, and also been changeing 5 litres of water every 3 days or so (no chlorine in) .. found a dead neon sucked onto the filter, stomach swollen and black looking... the betta seem'd quite unhappy and I'd done some reading and thought i'd give it a shot haveing him free in the tank, I was quite pleased to find things seem'd to be ok, he made a home for himself in the castle .... a couple days later I found one of the neons strugling to swim at the bottom, and was without a tail at all!! He seems to be hanging in there so far.. I moved the betta out of the tank back into a bowl, as he was the likely suspect.... this morning a found another dead neon sucked onto the filter, nothing looked wrong with it...... So anyway we're down to 3 neons, 1 without a tail, one looks fine, and the other is covered in white spots (ich I guess) and looks awful ... the Pleco seems to be OK, think it has a couple white spots on it though .. Frog seems great, always swimming around and jumping at the pleco ... I got a thing of aqusal but i've been afraid to use it, it says not to use if there's amphibians .. is it unsafe for the frog ? ... I've also been scared to raise the temp up to 85 .. can the tetra, pleco and frog handle that temp ?? ... is it safe to use the aquasal with the frog ?? ....... Thanks in advance, wrote this up real quick before dinner so I hope it makes sence ... I don't have a testing kit, I know this is a must .... I thought my tank would have been cycled by now, perhaps now ????
