I agree with the others who've posted, your tank is over stocked & that mix is not a good one to begin with. Tiger Barbs are very aggressive, especially in small groups and when the tank is crowded. Do any of your fish have ragged fins yet? Mollys should have a 30 to 40 gallon tank, although my son has a single Molly in his 20 gallon high with no problems. Neons are very peaceful & shouldn't be kept with Tiger Barbs either. Did you research any of these fish before you got them?
I would re-home the Tiger Barbs & the Danios, and then you could add a couple of female Dwarf Gouramis & a few more Neons or Glowlight Tetras. Then, if it's a Common Pleco they get to be up to 24 inches long, so you should trade him out for a Bristlenose Pleco or a small school of 6 Otos for algae control.
Hi, I currently have a 98 litre cycled tank (20-21 gallons) and my stocking at the moment is 5 zebra danios, 5 tiger barbs, 2 dalmation mollies, 2 platys, 6 neons, 2 dwarf gouramis and a rescued pleco. I was wondering could i add more fish, i was thinking of a female dwarf gourami/ guppies/ female bettas but open to other suggestions.
Sorry to burst your bubble, but this stocking is awful and overstocked
Zebra danios are very active fish and need at least a 4 foot tank
On no account should gouramis, neon tetras, and tiger barbs be in the same tank. Tiger barbs are super aggressive to other fish, especially long finned fish like gouramis. And what kind of rescued plec? If its a common plec, it gets waaaaay to big for that tank
Actually the tiger barbs stick together and not once have they bothered anyone in the tank. As for the neons they are the sooo placid. The pleco is a common one. So i don't agree with you "ON NO ACCOUNT SHOULD THEY BE PUT TOGETHER"
How big are the Tigers?
